Hello all need some help from the auto audio experts . I have a 2001 GMC one ton dually pickup that had an aftermarket Pioneer radio in it . I decided I wanted to change to an Android based head unit . The truck has no steering wheel controls or power windows or locks ........ she's plain Jane
When I removed the Pioneer unit I was pleased to see there was a factory connector used to splice in the unit . I took notice of the color wires and removed it . The Android based unit came with a harness and was color coded so I soldered all the wires together that made sense to me . I believe all I have soldered is the power , the ground and the speaker wires .
So after doing that I am left with the following unused wires . On the truck harness side I have a solid orange wire and a solid dark blue wire . The orange is not labeled the blue says " antenna " printed on the insulation . I think that is for a power antenna ?
On the radio harness side I have the following:
Solid pink wire labeled " back " but the chinglish instructions say it's for steering wheel control wires.
Solid blue wire the instructions say radio antenna power supply.
Orange/black wire labeled " key 1 " .
Brown/black wire labeled " key 2 " .
Solid orange wire labeled " lamp control " .
The seller ( Ebay vendor ) still owes me the back up camera and wiring that goes with it . I am guessing the pink wire labeled " back " may be the signal wire to tell the camera the truck is in reverse ? Any help understanding all these " left over " wires is appreciated . I have NOT plugged in anything yet as I prefer to be safe than sorry . And I will admit wiring in general is not my forte .
