What type of harness do I need to install a aftermarket radio in my '05 envoy?? It has the stock amp ( the amp is small) in it and OnStar.

This is where you are actually going to have to go to the Crutchfield website yourself and give it a go. Each head unit is different. No one can help you without any specifics. Go ahead, you can do it.

Crutchfield has good people there. If they can't make you satisfied, then likely no one can.
