Hey guys just making sure I know everything before getting into this install next week. (mechanical boost gauge)
Couple easy questions:
1) what do people usually do for the dimmer and ground wiring for the gauge? I would like the backlighting to come on with the headlights at night. It has red led backlights so it will look pretty good with the red setup I have goin on.
2) If your answer to question 1 is just wire it to the dimmer in the radio.... Can I still do this if my dimmer wire is not connected to anuthing behind the dash? I have a aftermarket pioneer unit with dvd and am not sure if I even have the dimmer wire wired to anything at all. IIRC there was one regular orange wire which i think is hooked up (using gmos-04 harness) and one orange/white wire coming from the head unit which IIRC I left un used.
Can I wire it to the orange/white wire will that work?
Additional info: Played around with the headlights to see if the head unit dims. I turned on my headlights and it seems the radio is always lit (not 100% sure).
So anything easier than using the dimmer on the head unit??!
04 gtp.
thanks
