I'm installing an amp and sub in my 2002 Chevrolet Blazer. I purchased a line output converter since the stock unit doesn't have pre-amp RCA plugs. I need the wiring diagram so I can hook up the line output converter to the left and right +/- sources. I also need to know the antenna or power line that will connect to my amp.

I've found resources for pre 2000 and 2004-2005 but these are different than what my setup looks like. Any help greatly appreciated! Thanks.

Should I call a Chevrolet Dealership? Would they have access to the stereo wireing diagram and be able to tell me the wire colors I need from above?

I have also noticed there are multiple wires of the same color. For instance, I may have 3 wires that are grey. Why are they the same color??

This would probably do better in the Car Audio forum where you first posted it. I'll remove your last comment and move it for you.
