2003 GMC sierra base model. No onstar at all. I just purchased a Blaupunkt 290MC 6.1 screen stereo. To me the wiring diagram is very vauge in the instructions. 1st-the park brake wire. it does not specify positive or negative. 2nd-key3 and key4 wire. i dont understand what these are for unless they are to power the back up camera or another add on.

All parking brake wires are negative. I have no idea about the other 2 wires.
