just received my boost gauge

[AdamRoutley]

just received this off ebay, quite cheap so i wasnt expecting instructions etc.

what do i need? obviously vac pipe and t-piece..iv heard you can get cheap tubing from b'n'q? moneys tight at the moment, so its being done on budget (as my holiday is in 3 weeks )

sizes would be appriciated too..also, with the wire..red, yellow and black..where should they go in the fuse bit? thanks adam

Sure that's a boost gauge?
Looks like it's a thread which means oil pressure as it uses an olive.
Take a pic ogf the front of the gauge.

 

[AdamRoutley]

its definately a boost gauge...its not a thread, its just like grooves so the hose doesnt pop off. what size tubing do i need from BnQ

 

[LEE69]

No idea mate generally 3-4mm but that's when the connector looks like this

sweet...got my hosing, and a T what about the wiring? yellow red and black? by the way this 1 has a button to change the colour so im guessing there has to be a cable for that?

the red will be +ve
Black -ve

Yellow Ignition Live.


I might have red and black wrong way though.

I think you should be right, but yellow maybe permanent and red ignition. was on an old mazda of mine

have now plumbed it in (apart from the wiring) and need to get a pod for it..but on a lil test spin, on full boost its going to around 7/8ish (psi) and on normal driving before spool up its down as far as it will go..

is that right for a normal LC (i have a open cone but thats it)

 

[AdamRoutley]

anybody?

 

[Rocky Rocastle]

yes mate that's about rite for an LC, i'd say 9ish. And yes coasting lets say you will be in vac -25, hit the accelerator slightly and it will spool to 0 after that boost to 9psi

 

[AdamRoutley]

sweet doood..thats all my questions answered! now to figure out this wiring milarky!

 

[J0N]

Red=Switched Live,
Yellow=Permanent Live,
Black=Earth.
(Probably).

 

[AdamRoutley]

spoke to the guy i got it off..

red - positive
black - negative
yellow - ignition

how do i connect the wires to the lighting section? do i just disconnect the battery first, then pull the corresponding wire out, wrap the boost gauge wire around it (ie, red, to a constant live) then plug the two back into the original slot?

 

[J0N]

Open the driver's door, remove the fuse box cover and then unbolt the fuse box so you can get behind it. When you've done that you can easily see the back of the light switch. Push the switch assembly out from behind and then you can get to all the wires.

Have a look at this thread too, http://www.seatcupra.net/forums/showthread.php?t=221220
There's a pic kindly posted up by FishmanUK that shows which wires are which.

cheers johny jonjon.. those guides seem good..just one thing confusing me, people keep using the term "ground" would i plug my "negative" cable in the same as people have plugged their ground into?

have found this pic on pabs guide.

http://www.seatcupra.net/images/leoncupra_guides/gauges/wireconnections.jpg (his red is his positive and the black is the ground) i think i'll probs do it this way. but where would my "ignition/yellow" cable go?

thanks, Adam

 

[LEE69]

Yes ground is earth/negative.
