Here are some photos for Gatorblue; if you need more PM me and I'll send all I have. I had a twist tie around the radio group to keep track.

The green/black wires are stock speaker wires and have a funny, small plug to upper right corner of radio back.

Underneath is a small black wire coming from the radio, attached to a blue quick connect = power wire. There is a in-line fuse further down this wire.

Next over is the thick grey long plug that fits in the deeper hole for antenna.

Then a bolt holds on a brown wire that ends in a loop, believe to be the ground wire.

Hope that answers it
