Hi all-this is my first post and I need some help. I'm looking for a wiring diagram for a 1990 Grand Am LE and also can anyone also tell me where I can find/how I can access the ignition switch harness. I'm trying to install power locks/keyless entry/ignition kill switch. Thanks.

Thanks shortdogchap, that was really helpful. If anyone else out there knows how I can access the ignition switch harness I'd really appreciate it.
