Thanks for getting back to me. I have the harness's for both. No one (Audio Installers) has them configured to match, that's why I posted the wiring diagram from Eonon unit. My question is. What do the GM wires hook up to on the Eonon wiring diagram provided.

Please Match this up to Eonon wiring diagram. At this point what I'm requesting should be obvious. Again thanks, I hope this will be answered.

You go to you local stereo shop or Amazon and get a wiring harness adapter kit. This you wire to the stereo and then it simply plugs in. Here are both wiring diagrams for amp and no amp models.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Cheers

A harness adapter to you do not have to cut any of the cars wiring harness as this will cause problems and be a real mess. The harness adapter should also tell you what wire does what connect them in that manner and then simply plug it into the car. If need be go to Crutchfield on the internet. Here is a pic.

Electrical problem

Hi I need to know what colors go with the wiring system for the stereo on a 2001 Chevy Blazer, I'm trying to hook up an amp and sub woofer and need to know the color to cut and add into a high low converter, the color I need is the rear speakers on the back of the stereo.

Thanks CJ

I had got my blazer back and I was checking if the main harness was there but it was cut off and connected to a radio and I wanted the harness there so when I buy another harness to clip to the main harness I wont have to worry much of wiring connections

I'm not sure what you are asking, but it is common for people to cut the OEM harness when using an aftermarket radio.

You could try to locate a used harness that matched your original and wire it in? Or maybe they actually make aftermarket harness replacements?
