Ok so he cut the factory harness off on one part but the other is connected. Were is the part he cut off just hook them back together and get his stock on in. Sounds like you are trying to add a stock cd player to that and odds are it might not work. You will need some kind of a plug, you can prob getto rig it though. And just trial and error. Find your power wires etc and ground. Take the ground hook it up to the car someplace and then take the 2 power wires the constint and acces and hold them together and touch the prongs on that other cd player till it turns on then just fade the hu to fron left. And use the wires to test untill you get the front left speaker to play, do this for the rest of them.
