Like always, I just want to take some time and thank you all for checking this post. THANK YOU... I have a 89 gxl and wanted to put a new headunit. Well the big problem is that the car was stripped of all speakers, wires. The last owner left the wires for the headunit intact and left his aftermarket wire harness plug. I searched for the wire colors and what each one corresponds to. Unfornately all pictures from perious post have been deleted.
Can anyone please give me a diagram of what the wires are colored coded to? Thank you

 

stereo wiring is in the FAQ at the top of the page and in the FSM...also in the FAQ.
