Wire harness to switch from stock stereo to cd player will not fit the wires that are supposed to? so what wires are the speaker wires


Not sure I understand your question. Did you buy a harness adapter for GMC, or are you trying to just cut the connector off the factory radio and solder it to your CD player? If the latter, below is the color code for your factory wiring.

Installing an aftermarket stereo, spliced the wires and have everything connected including the remote wire to the factory amp wire but still no sound.


There is no remote wire on these newer trucks....03 and up....u have to buy the harness....although i didnt....i have an 03 gmc sierra and just pulled the schematic and matched the wires. And there is no programming to do on an aftermarket stereo.....I work for GMC and we cant program aftermarket stereos......if u buy the right harness ...and its over $100 then everything should work just fine.....and this does not disarm ur alarm system either....mine still works fine....hope this helps
