Installing Aftermarket radio Help!
 

Okay so I have a 2002 Monte Carlo SS with on star and an amplifier in the trunk. I am very knowledgeable with wiring, but I dont know what all I need, or what I do not need to get the job done. I have uploaded pictures of the stereo that I purchased, and it also comes with the steering control harness with the radio also. If anyone could give me some advice I would greatly appreciate it. Also I am not too worried if on star is active or disabled. and Im not all sure about what would happen or the results of not having the chimes active?

you also need another harness...i think it was a GMOS04....something like that. hopefully someone can give more insight

I used one I bought from walmart. I believe it is this one. Scosche GM2000 Class II Car Stereo Replacement Interface Module and Harness - Walmart.com
I have had it for three years since I put in my aftermarket radio in it and have had no problems with it.

Well I bought the gmos one for 40 bucks,the wiring harness, but I didnt but the amsc kit for steering control buttons. How did you get by with that

Hey Guys,

Is the Chime box harness and wheel control harness simple plug and play?
