I have a 95 gmc sierra 2500 and im trying to put in my aftermarket rafio so i cut the stock harness out the square puece that goes in back of stock radio and now i cant figure out what wire is what i got...


I would suggest you spice the wires back to stock harness by male and female connections and tape over them with black tape then get a stereo install kit that includes a wiring harness ( cost about $20 maybe or less) for the year of truck you have... it will plug right to your stock harness ...never just cut stock stereo wires from stock plug it will be more of a headache than you think trust me I've installed all my own stereo system been there done that... good luck

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
