Thread: boost gauge install questions!

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

im not sure on anything but i can tell you that your radio is always lit. i also have a poineer unit and it is definitely always lit.

ok thanks i will give this a try. hopefully this way will work for me.

Uhhh guy.

Mechanical boost gauge.

Not the aisle 4 autozone ricer sunpro crap.

Yup, I see that.

Two boost gauge threads from the same guy lost me.

technically one is for wiring the other is for vac/boost

I did the vent ball mod since i have an 04... if i went 3 pillar route i would have done boost, aeroforce, and somthing else...but i use torque so stuck with just a mech boost gauge.
