Delco Stereo With Aux Input

This is an early Theftlock stereo removed from a 1996 Chevy Cavalier. The radio was removed in favor of a better system and given to me to play with. I have a personal collection of these stereo systems, and I decided that it was time to figure out how to add inputs to them. This is the first one I have done that's from the "Theftlock" generation of GM Stereo systems. I used standard ethernet cable for the switch. I used a simple DPDT switch to cut the audio off from the radio tuner, to the amp section of the radio, once cut by the switch, I merely replace the audio signal with that from my computer.
