Doesn’t work but here’s how you fix it on a 2002 Chevy Avalanche I matched up the wires color for color to my Pioneer 8700 (using 3M gel connecters took 5 min!). I removed my old deck and this harness plugged right in. The deck turned on and seamed fine except I had NO sound coming from the speakers (sub worked with RCAs). I thought for sure the speaker wires were wrong so I double checked the schematic. Everything was wired correctly. After many hours of research, I figured out that the Blue with white stripe (amp turn on) wire from the new deck needed to be connected to a pink wire from a now disconnected wiring harness, that had been previously hooked to the back of the factory deck. This sends a signal to the truck’s amp to turn on and power the door speakers.You’re welcome!

2002 Chevy 1500 +++++ Plugged right into the wire harness of my 2002 Chevy 1500 with no issues and the wire colors matched the head unit harness exactly making the new radio install very painless. I just soldered the two harnesses together in the house matching all color wires together after verifying wiring diagrams and simply plugged everything into the truck with no issues.

Don’t waste your time and money. Poorly Constructed. If I could rate 0 stars I would. First of all the pins were not making a snug contact. The pins were to thin. If I moved the harness at the point were they plugged together it would work fine. I had to remove everything to double check the harness. Then I noticed 2 pins for the left front and right rear speaker were snapped off and barley hanging on. Jetta used to make Solid products. I used them since my first install…. not sure what’s going on now.
