someone please help me ?
or is there someone i can call?
mabye one of you who have done it

 

Waaaay too few details brother:

1) what year is your G35 (sedan or coupe?)
2) Are you using the Metra 7551 or 7550 harness?
3) Which Pioneer headunit?
4) Why do you need to know where the brake wire -- do you mean parking brake?
5) Why don't you BYPASS the parking brake wire or just connect it to GROUND wire?
6) Metra colors are available online at various resources, including Metra's website.

 

Oh, and I have installed the pioneer F90bt unit (POS, but hopefully you'll have better luck! LOL)

 

if you have a aftermarket harness

yellow is 12v contants
lime green is parking break from unit
black is gound
red is 12v switched

 

Please read instruction manual. All information is in there... parking brake wire goes to your car's parking brake.
Many people think this is easy. It's only easy if you've done it many times before and know how to troubleshoot problems. I know it sounds mean and harsh but it's the truth. If you're going to do it, ask questions beforehand so you know what you're in for.
