I just picked up an 89 Trans am and one of the previous owners rigged up the battery for a high powered stereo system. I'm wanting to take all that out and have the original negative and positive wires from the battery. With this being said I'm not quite sure where the original wires went From the battery. Any help would be appreciated. I have also been looking around for a wiring diagram but if someone could tell me or show me pictures of there car that would be fantastic.
