Boost Gauge wiring black/red

[mwflynn06]

Got a boost gauge and it only has the black and red wires. Just don't no where the black and red wires go in the back of the light switch. Anyone shed ant light on where to correctly wire it up.

Red was live black was ground on my boost gauge ... Ground can go on the chassis ... I put my elec meter on each terminal... And turned the headlights on and off till i found the correct wire to tap into ... Hope that helps

To be honest no ,, but where is that connection point that your thinking of tapping into .. I took that panel off on the right hand side of the steering wheel ... And traced cables to the light switch .. I'm currently in derby working when I get bk tomorrow I can take the cover off and take a pic for u

I it only has two wires, it's probably an electric guage and wants a switched live as opposed to a feed from the headlights

Yes you can get the switch live from that panel ... When u turn the lights on the gauge goes on and off

That be brilliant if you can do that. Just want the gauge to light up when I turn on my lights. Dont want it lit up constantly.

Thats not a switched live. Thats a feed from the light switch

Well i used a switch live , i used my electricians voltage pen and lights up and off with the toggle switch for the lights ... So that would be a switch live ... That's what i used and it worked

So your boost gauge will only be on when the lights are on???? A switched live, means a live that is only live when the ignition is turned on. There should be one on that plug.

Boost gauge lights will only be on when my lights are on IE headlights im talking about ... Why would i want the lights for the boost gauge on during the day .... When your switching the lights on IE when u turn that switch to right ,, the switch live go down to the headlights which is what i have joined into for the LIGHTS on my boost gauge ... They are not permanently fed as they would be continuously on

You never specified. I now realise you have a mechanical boost gauge, with wiring for lights. My mistake, i should have known that.

Yeh but if the OP only has 2 wires, theres a good chance its not a mechanical gauge. Which was kinda my point at the start

Its a feed from the headlights. A switched live is live when you switch the ignition on

Found one of these in my tool box never even new I had it.

Looks like it lights up when on a live connection. Could I just use that to see which wire goes live when the light switch is on ?

What gauge is it you have ? I've recently fitted one with only black and red wires...although my gauge is lit up when ignition is on ( gauge is completely black when not lit up unable to see anything) wired it up nicely and works with dimmer.

Was just off eBay and only has the two wires unlike alot of the threads on here which have 3. Not too fussed if its lit up all the time but would be nice so it only lit up when I turned on my lights. It has a white face so during day its easy to see.

Understood. No that it's much help but whilst I was wiring it up trying to get it to work i did get mine to light up just on lights. But no idea what it was.
Mine are:
Black to brown.
Red to blue/grey... you should try the other half colour ones... It doesn't do the wires and issues if you have the time..I crimped all my wires before finding the correct one :/...
