Auto Gauge boost gauge. How to wire up correctly!!!!

[godber225r]

Seen lots of threads on here about wanting to know how to wire up the halfords auto gauge boost gauge. lots of people wanting to know what wire goes where so here it goes!!!:)

This is a guide on the correct way to fit/wire it up so you get it to light up and save the setting you last had it on, This does work as its the way i wired it up to my car and it works how it should.

1. Get some silicone 4mm inner diameter pipe about 3 metres worth.
2. T it from the FPR.
3. Drill hole in the grommet hole next to the main wiring loom under the scuttle panel but dont push the drill in too deep pearce your way through the foam with a screwdriver carefully
4. Push pipe trough hole and retrieve from the inside ( this takes alot of time and patience!!!) put a big blob of silicone around the pipe going into the car.
5. feed it up to your pillar pod and push into gauge.

Wiring THE CORRECT WAY.

Obviously extend all the wires from the gauge!!

6. join the black gauge wire (earth) to the brown wire on the light switch block
7. Join the purple and orange gauge wire(switched live) together and then join it to the grey wire with blue tracer on on switch block
8. join the yellow gauge wire (positive) to the fat red wire on the light switch block.

The gauge will light up when you put the ignition on. It will also dim when you use the dimmer.:)

The gauge readings (for a standard map 225) were 14 psi or 1 bar peak and 20 inhg

Hope this helps and clears things up for people?:D

Comments as usual are welcome?!

[Sportrider]

why couldnt you of put this up about 4weeks ago when i was struggling to fit mine lol :cartman:

should be made a sticky i think

[Seat Gooner]

sounds good to me mate im going to use this guide soon :D thank you

[Rocky Rocastle]

Nice guide :clap:

[BoomhaueR]

Good guide.
If you find the gauge buzzes on boost, then buy one of these and put it next to the gauge:
http://www.awesome-gti.co.uk/product.php?xProd=6778

One thing I found tricky was getting the wires out of the switch block/loom. How did you get them out to splice to the gauge wire?

[J0N]

Thats a good guide godber225r. I'd like to add the wiring for the oil temp and if someone wants to use the info to make a sticky feel free.

This is for the Auto-Gauge (Halfords) oil temp gauge.

Gauge Lighting. (These wires are on the back of the gauge).
Thick Yellow - Permanent Live 12v,
Thick Purple and Thick Orange - Twist them together and connect to a switched live. (One that becomes live when you switch your lights on.)
Thick Black - A Good Earth.

Gauge reading. (These wires are also on the back of the gauge).
Thin Black - A Good Earth. (Twist together with the thick black).
Thin Green - To the Red (or sometimes it's white) Wire on your sender.
Thin Red - To a Permanent Live 12v (Twist together with the Thick Yellow).

The Sender. (These wires are on the actual sender).
Red (Or Sometimes White) - To the Thin Green Wire as mentioned above.
Black - I connected mine directly to the battery negative (-).


It's especially important that you connect the thin red to a permanent live, if you connect it to the switched live from your lights it will read slightly lower than normal and the needle will go up and down with your dimmer switch.
Do all of this correctly and the gauge should remember what colour it was when you switched your ignition off (although these Halfords gauges don't always remember no matter how you wire them up) and the temperature needle should still read with the engine/ignition off.

Hope this helps, worked for me but if your car catches fire I cannot be held responsible.
If anyone thinks I've got it wrong please let me know, we don't want any disasters do we?

The electrical wiring for the boost gauge will be the same colours as the oil temp and I just wired them in together.

[godber225r]

Cheers guys thought i might as well do a guide for it as it saves allot of time and confusion. I had a oil temp gauge as well from auto gauge but decided not to fit it but it had exactly the same colour wires coming out of it so probably wire it up the same as boost gauge.

[godber225r]

It would be really nice to have this as a sticky too!!!! :)

Whoever deals with that!!?????:shrug:

[AdamRoutley]

so to accompany your write up, this is how you connected the following cables?

When you say the "grommet" next to the wiring loom, do you mean the plastic circle to the left of the wiring loom that looks like an optional piece of kit?

[CupraUK]

http://i177.photobucket.com/albums/w225/spudisdabest/switchedlive2.jpgWhat is this connector block? Is it in the fuse box?

[seatcupra2001]

What is this connector block? Is it in the fuse box?

also can i add will the instructions about the oil temp guage is this how to get the reading????? coz ive had oil temp gauge an still dont know how to fit it?:banghead: please help me:cry:

[LEE69]

What is this connector block? Is it in the fuse box?
It's the rear of the light switch.

Good guide mate.... will use this to fit my boost guage in a few weeks. I'll have to look for the wiring loom hole as I thought most people took the pipe through the boot release wire gromet.

Just a quick question to save me starting another thread.......

I have a boost gauge fitted but it only has 2 wires [obviously live and earth]

I now have a new gauge that has 3 wires-

1. permanent live
2. switched live.
3. Earth

The guage is a single colour and nothing fancy so I'm not sure why it needs a permant live?? Its one of the ones thats a blank face until you turn the ignition on then it lights up.

Am I right in thinking I can join the Permanent live and the switched live together and join them both to my current switched live? would be good for me as I already have the 2 wires in the pillar from the current gauge.

I don't see why not as you have no colour to "remember"

[adam cupra 20vt]

Thats what I thought, seems a bit strange that it needs a permant feed, hopefully it will be here tomorrow so I'll try it :)

yes, join them together the same as the purple and orange on the Auto-Gauge. The reason for this is because the instrument lights on SEAT's come on when you turn on the ignition and not just when you switch the lights on, on other cars you would probably have to connect one to a switched live from the lights and the other from the ignition.

[adam cupra 20vt]

Thanks I will do if it ever turns up! :D

[CupraUK]

UHHHH.... just broke my windscreeen trying to remove the windscreen wipers to do this! F*kin great.

For sale; one auto guage + pipe

[adam cupra 20vt]

Sorry to hear that mate, did you use one of the removal tools?

[CupraUK]

I don't really know how to remove the windscreen wipers, so I was just carefully testing to see if it leavered off, obviously not carefully enough

[adam cupra 20vt]

You usually elevate the wiper and twist it until it comes off.....but its a bit late now. lol

Atleast you'll get a new window and the wipers will no longer be stuck as they'll have to take them off to fit new screen.

[LEE69]

What a pain, you fully comp?

[CupraUK]

Yeah, £75 excess

[LEE69]

Better than having to pay for it all.

[CupraUK]

Yep, sale of gauge will have to cover some of it though

[Moffat]

I'd just like to add, incase anyone's interested, that on the 4 wire Autogauge ones, where mentioned that you need to join the Orange and Purple wires together, You dont really. It depends how you want it set up. I can't remember which way round it is, but one of these wires is the face illumination for the gauge, and the other is the illumination for only the needle. In my last car i had mine wired up so that the needle illuminated with the ignition on, then the face didnt illuminate until i put the lights on. I know the dials are always illuminated on the Leons, but i just thought i'd mention incase anyone is interested.

[adam cupra 20vt]

yes, join them together the same as the purple and orange on the Auto-Gauge. The reason for this is because the instrument lights on SEAT's come on when you turn on the ignition and not just when you switch the lights on, on other cars you would probably have to connect one to a switched live from the lights and the other from the ignition.

I have installed it, joined them together and it works a treat...looks much better now it matches the rest of the dash lights to.

[J0N]

Very true, but this is in the Mk 1 Leon section. :D. Valid point though.

[nutter_engineer]

Altough not a wiring question, just wondering how did any of you replaced the standard tubing with a proper silicone one? Is the standard tubing up to the job or should it be replaced? In one of the other threads, it mentions the tube runs all the way into the guage so you have to run the clear tube into the silicone tube, is this so?

[J0N]

I just used the tubing supplied.

[LEE69]

The standard stuff is very thin walled, thicker stuff is better for vacuum.

No, just replace the whole tube in one go throw the clear stuff away.

[nutter_engineer]

Yeah I was thinking about getting some decent silicone for the job. what size should I be getting 3mm, 4mm or 5mm? Also, I was reading some other post that the clear tube is already connected to the gauge when you buy it and cant change the tube, hence running the clear tube inside silicone tubing, is that correct?

[LEE69]

I used 4mm.
Not in my case with the gauge it wasn't attached.

[gex18]

I know this is in the leon section, but I thought i'd ask anyway.

I have just bought an Autogauges boost gauge with stepmotor movement for my MK4 Ibiza Cupra. Now according to the OPs guide it should have

- Black Wire (Earth)
- Purple and Orange wires joined together
- Yellow

My gauge, however has the following :

Red - Battery (+)
Black - Engine ground
White - Ignition switch
Orange - Dimmer / +12v to dimmer.

So, is it as follows regarding wiring to the lighting panel

Gauge Lighting panel

Red Red
Black Brown
White ????
Orange ????

Can someone help me out here?:confused:

Many thanks

Anthony

[S17EW O]

cheers guys this is a great help. round 2 tomorow

[godber225r]

The search function really works!! :):):):):):)

im glad this guide has helped lots of people!!

[S17EW O]

guys....made progress...have got an auto gauge from halfords and wired up to the back of my lights switch following this very good thread. Next problem was that at first everything worked perfectly and it remembered the colour I set too but after a short spell the red of the digits dimmed but not the needle and then I could not change the color. The pin did nothing. Then to top it all it started changing to blue on its own. now its stuck on dim red lights appart from the needle and pin does nothing!?Does that sound like a bad connection or faulty gauge?

[LEE69]

If you are 100% sure the connections are good, it will be the gauge.
How did you connect the wires?

[J0N]

Thick Yellow - Permanent Live 12v, this is so it 'remembers' what colour it's on.
Thick Purple and Thick Orange - Twist them together and connect to a switched live. One is for the backlight and one is for the needle, can't remember which is which but it does'nt really matter on our cars. This is because on some cars you might want the needle lit all the time and the backlight to come on with the lights, etc. Although our instrument lights come on with the ignition you still want the purple and orange connecting to a switched live so the gauge stays lit with everything else when the lights are on but the ignition is off.

Also there is a setting on the gauge that keeps changing the colour, I suppose some people like it like that but it's also worth remembering that these gauges are not of the highest quality and can change colour of their own accord. I used to have both of mine set to blue because they matched my HU but one of them kept changing back to red even though they were wired in together, now I just leave them on red.

[S17EW O]

Well I had the wires soldered in. Will double check them though. Now you've said that I'm considering disconnecting. One of those wires because personally I think the needle is far too bright and I think u would still see it fine with just the backlight. What do you guys think?does anyone no which I disconnect?

[godber225r]

I would say you have a faulty gauge mate. I used bullet connectors to wire mine in and it worked first time and that was nearly a year ago and i have had no problems since.

If you wired it like a said on page 1 you cant go wrong it is the correct way to wire it up. I think the purple is the needle wire. as one is the needle and the other the backlight (orange)

I wouldnt say the needle is not that bright? can you use the dimmer? it will work with the gauge.

[S17EW O]

Na I think the needle is too bright. In comparison to the backlight. The dimmer works a treat. Would you no how to wire it so as the dimmer dims the boost gauge but leaves the normal gauges at full brightness?

[J0N]

Na I think the needle is too bright. In comparison to the backlight. The dimmer works a treat. Would you no how to wire it so as the dimmer dims the boost gauge but leaves the normal gauges at full brightness?

I would'nt start messing with the car's wiring, if you're finding the needle too bright just disconnect it.

[SalSheikh]

I still want this as a sticky!!!

me too!

[godber225r]

I wouldn't mess with the cars wiring. But you could if you realy wanted put a separate dimmer in just for the gauge. Im sure you could get one from a electrical store like maplin etc??

[wayne lcr]

i have done this but mine dunt remember the colour ? i have to press the button to change it to red what have i done wrong:(

[godber225r]

Have you made sure you connected the yellow gauge wire to the fat red wire on switchblock as this
is permanent live you need for memory? Have you double checked connections are good?

[k_pt]

one thing I dont understand
in some tutorials on the net is, theres a T on the installation ... shouldn't only go a tube from the IC pipe to the gauge?

(edit: I going for tdi pd)

[stevekkk1]

whats an fpr and where is it?

[LEE69]

Mines in the FPR (fuel pressure regulator) follow the blue hose ;)

http://i174.photobucket.com/albums/w91/LEE_69/Leon/Engine/DSCF0316.jpg

[stevekkk1]

fitted mine at the weekend, took me 6 hrs but got there in the end, i used a long screwdriver for getting the vacuum pipe through the bulk head into the footwell, worked a treat, just taped the pipe to the end of the screwdriver and gently pushed it through the grommit. great instructions, very easy to follow

thanx

[collins]

hi guys,have managed to get the electrical side all wired up and working but cant see at all where the vac hose comes into the car,have drilled the grommet carefully and everything but cant see it at all inside the car,even with the fuse block removed and peering into the back of the dash,can feel some foam though.any ideas??

[LEE69]

Feed the hose into the car and it will fall in to view, if it doesn't put your hand up in the direction, should be easy.

[stevekkk1]

have you removed the trim underneath the steering wheel?

[collins]

have you removed the trim underneath the steering wheel?

no not yet,you recon to just take off the kick plate trim and i will be able to see it then?i just tried through the fuse board side on the dash.will give it a go next weekend then

No the under dash trim

Hey all,

Sorry to resurret this thread, i have bought a new digital LED boost guage, http://www.rspec.co.uk/index.php?main_page=product_info&cPath=3_103&products_id=469

I need to confirm with somebody the wiring as its slightly different that any of the ones i have searched for on here.

It has the below:

Yellow = Battery (+)
Red = 12v+ Ignition switch
Black = ground

So if i read this thread right, my install should go

Yellow to fat red wire on the light switch block.
Red to grey wire with blue tracer on on switch block
Black to Brown

Is this correct?

I only had 2 wires on my boost gauge, a red and a black one, I unplugged the TCS/ESP button, and wired up the 2 wires of the boost, dont make connection with ignition on, you will burn a fuse (like I did lol) if you wire it wrong ... but if the ignition is off and you turn it on, even if its wired incorrectly, theres no problem :)

TCS/ESP plug has 3 holes, you'll just have to find out wich of them are de pos and neg, i just inserted the wire on the plug holes, and plugged it to the button, fixed and simple

Its working perfectly.

To pass thru the firewall, find a little rubber on the left side of your engine bay (on a LHD) near the electrovalve box, the black box with lots of hoses, take of that rubber and stick the hose to you get to the side panel of the dashboard, then bring it to where you want it

if need, i'll post some pics

Since this is a digital gauge and won't have adjustable brightness there is an easier way than tapping the light switch; take the lower dash off on the drivers side, you with see the main power distribution blocks; crimp holed crimps onto your boost gauge wires and add on to this terminals, red to yellow and yellow to red. Above and to the left is the dash board earthing point; black to here. Ensure you use inline fuses where appropriate (yellow wire on gauge). Disconnect the battery before doing this.

Otherwise, from memory what you have said does look right :)

The distribution block you will tap into is not fused..hence you need a fuse between the gauge and the dist. block in the permanent live. Switched live dist. block is fused already IIRC.

All done now. Its wired up so that the gauges only light up when i turn the lights on, ie when its dark. There also controlled by the dash dimmer for brightness. All done now.

You don't get them out you just "piggy back" onto them.
Either solder the new wire to the one you "need" or cut the wire and use crimpers/electrical connectors/chocolate/amp blocks.

godber225r wer can i find the fpr pipe? 9ve wired mine in n its permenantly runs in -2.0 to -3.0 cud i have put it into the wrong pipe from the turbo?

What car you got? take off the engine cover its on the injection rail on the right hand side looks like a dump valve but its not!!! (Thats the FPR) has a pipe coming off it T into that and cable tie the pipe across the rail and around the pipes to go up into the bulkhead

You have your switched and permanent live the wrong way round. Wire it up as original post and it will work corectly

Sorry to bring back an old thread but have a few questions.

Had my AutoGauge Boost gauge setup and working for about 6 months it used to:
remember last selected colour
dim with light dimmer etc
generally working as expected

but recently it has:

started forgetting the last colour

when cycling through the 7 colours it will get stuck after the first repeat of the 7 colours i.e. after 8 clicks it them stops changing colour and doesn't start working again until you leave ignition off for a while occasionally it will start working after switching ignition off and on immediately.


Also the needle always sits at about -2 and always has which is annoying


I have check the fuse t the perm live and checked connections (as best i could as the wires are in crimp connectors and are now taped up to stop movement. If this likely a fault gauge or a faulty connection?

Also will halfords replace it after 6month (i do the have receipt)

cheers

ive got my new glow shift gauge from the usa, just reading the instruction for fitting and it states it shouldnt be used with a dimmer, what way should i wire it up then? i assume the light switch itself has the dimmer unit built in?

Sorry for another thread resurrection, but I'm having issues with the Autogauge 3-wire boost gauge!

The gauge lights up with ignition and when the dimmer is not on full power lights up as white but wont change colour....then when I put the dimmer to full power the light turns green and will change colour briefly when i press the button on the gauge but reverts back to green and flickers constantly thereafter :S

I've wired up as below:

Black wire - brown wire in light block
Red & Orange(or Yellow) - connected together and wired to grey/blue wire in light block

Should i connect the orange wire to the fat red wire as indicated in earlier posts? I'm just unsure why the dimmer switch is interfering with the signal!

Thanks in advance guys.

BUMP!

I've re-wired as per the 3-wire guide (Red to grey/blue, Black to brown and Yellow to thick red) and the light on the gauge now dims correctly but still flickers after i've started the engine and won't hold the colour when i've selected it :shrug:

Could it just be a dodgy gauge in need of replacing? I've checked all the wiring connections and they're all solid, not sure what else it could be...

[dgjdrummer]

Bumpity bump!

Anyone? Gettin hacked off with my gauge now, have checked the wiring and tried the dimmer switch on various power levels, only lets me change colour with the dimmer on full (engine not running) and flickers if the dimmer is on full once i start the engine :confused:

[TheBigGM]

Sorry to be totally thick but where can you get the extended wires from? I'm assuming we will need like a junction box to connect these together? (this is relating to the original post by the way)

[shadyshades91]

sorry im a newbie wot does fpr stand for and i carnt find the diesel section did u mean in tht pdf or on here lol

[shadyshades91]

the big GM i would extened cable cud cause a loose in connection or cause a leak id re-wire it with the correct length of hose or wires needed i never recommend joining cable i work in a electric shop and the amount of customers that have ****ing things up with joins here there and everywhere.

if the light is flickering i would guess at a poor connection sumwhere or interference, but if you have checked you wires and connections then my guess is the gauge is faulty.

i wired my gauge in using this thread a few years ago and didnt have any problems, it did go through a stage of not staying on red after ignition off on again but that has seemed to clear itself up without me touching it

if you can exchange the gauge

Ah ok, I've checked the connections and even changed the cables themselves to ensure there were no splits or interference but it still reacts the same. The gauge came with the car so unfortunately I'm stuck with it :(

Cheers for the help though mate.

[mcdatkyid]

im a newby on here and this is a great guide! il be fitting it tomorrow.....or at least trying lol

[cuprastoffs]

What is the general feedback on these gauges? Accuracy mostly as they are rather cheap. :think: Been looking at the new defi but quite pricey.

Fitted my auto sport gauge Wednesday and it was a right mission loool!


I have the one that sits in your drivers ride side air vent. I had to drill a hole through the gromet Under the plastic cover beneath the drivers window wiperand try feed the silicon hosing through. Taking the dashboard to peices under the steering wheel finally managed it! Wiring it up was a little easier :-) took it for a spin and my readings were a vac reading of 20 on idle, 0 when reving it stationaryand boosts to 18 psi giving it death!

Looks great too with the choice of colours !!

[prittchauhan]

could you please post a pic of where you pit the T piece in please,

just bought a auto gauge from halfords but aint got clue so i would like to se a pic of T piece fitted on the FPR

ive got a standard leon cupra 1.8t 20v facelift if im right (no the R version)

thanka

Seen lots of threads on here about wanting to know how to wire up the halfords auto gauge boost gauge. lots of people wanting to know what wire goes where so here it goes!!!:)

This is a guide on the correct way to fit/wire it up so you get it to light up and save the setting you last had it on, This does work as its the way i wired it up to my car and it works how it should.

1. Get some silicone 4mm inner diameter pipe about 3 metres worth.
2. T it from the FPR.
3. Drill hole in the grommet hole next to the main wiring loom under the scuttle panel but dont push the drill in too deep pearce your way through the foam with a screwdriver carefully
4. Push pipe trough hole and retrieve from the inside ( this takes alot of time and patience!!!) put a big blob of silicone around the pipe going into the car.
5. feed it up to your pillar pod and push into gauge.

Wiring THE CORRECT WAY.

Obviously extend all the wires from the gauge!!

6. join the black gauge wire (earth) to the brown wire on the light switch block
7. Join the purple and orange gauge wire(switched live) together and then join it to the grey wire with blue tracer on on switch block
8. join the yellow gauge wire (positive) to the fat red wire on the light switch block.

The gauge will light up when you put the ignition on. It will also dim when you use the dimmer.:)

The gauge readings (for a standard map 225) were 14 psi or 1 bar peak and 20 inhg

Hope this helps and clears things up for people?:D

Comments as usual are welcome?!

Any idea what gauge should be reading on a .cupra 1.8T 2002 AUQ engine,only mod Forge 007P Valve & Green cotton Panel filter ?
Reply would be great.
THanks

My readings are 20 psi vac at idle. Rev the engine and it is around 0 psi. Go out for a spin and it hits 12 ish psi. that seems low?

Is that on std. 1.8t engine ?
I seem to be getting the same at idle,std.sort of rev. about zero and up to about 11-12 on boost,about the same,must be about right then.:shrug:
