I'm installing a Pioneer AVIC-F90BT in a 2002 Tahoe (With OnStar, without Bose, OnStar is not being used). I swapped out all the speakers and am amping them (4 speakers, 2 subs). I'm converting the dash to a 2din opening, but I didn't bother buying a wiring harness adapter for the head unit.
I need to tap into constant power, accessory power, ground, VSS, and illumination. Does anyone know which wires these would be on the two harnesses that plugged into the factory radio? Are any of the other wires in these harnesses essential?
I apologize if this is a repeat but I couldn't find any wiring diagrams by searching the forums. Thanks for all help.
