ok i apoligize in advance i know this info is on one of the fourteen pages but i dont have alot of time before i need to go back to work but.... the retards who installed my d2 didnt hook up the parking break what so ever soo i can only use half the functions on my unit. if you guys could please tell me what i need to do to get all my functions working and possibly working while im driving it would be awesome..... once again sorry i know everyone answers this stupid question all the time.

There is an empty hole in the D2 harness. Find an extra wire and pin that you are not using, or use an extra wire and pin from another harness. Stick that extra wire/pin in that hole. Ground that extra wire and the light green parking brake wire
