alrighty then, dad brought home this old radio from 2004 it looks like. It's a delphi delco model and the p/n is 20820699 it was out of a big rig, because it say peterbilt. well theres no power cord for it and it like 3 seperate places for one in the back. So i'm not familiar with this radio. But i wanna make it work, therefore i dont have a radio in my truck and this one was free!! lol.
