Hey guys i just bought a boost gauge and installed it where the ash tray is, and i was thinking of using the power off the lighter, but im not to sure which wire to use out of the 3. Has anyone done this before?? I have a 99 1.8.


Thanks,

iirc you should wire it to the x75 - you want the light to turn on when the car is switched - i think the lighter one only turns on when your head light is on - i could be wrong - but just go out and check - if the lighter turns on when you turn your car then you can get some power from there - but don't be lazy and just get the powe ryou need from the x75 termal or whatever its called

If the ash tray or lighter lights up when you turn the parking lights on then that will work. The 3 wires are going to be 12v, ground and parking lights switched. Best thing to do is just get a test light and test the wires to see what they are.

You can extend the ground wire or just use the ground of the lighter. The best place to put your ground is a ground block, there is one right behind the hood release handle on the metal just above the kick panel.

so out of the 3 wires that plug into the lighter there will be a ground? so i could attach the 2 wires from the boost light to 2 wires from the lighter?


Also should what should my psi be around its right in between 9-10, i just have an intake on it.

Thnaks,


Do you know what color the 3 wires are in the ashtray?

Yes 1 of them will be a ground to finish the circuit for the lighter plug.
