91 Trans Am and 87 IROC pinouts

Working on my project 87 IROC... Does anyone have a detailed wiring diagram of the firewall (from fuse panel) connector pinouts for a 91 Trans Am and a 87 IROC? I need to know what slot positions the wiring harnesses and accessories etc. are assigned to. The interior harness I'm useing is out of a 91 Trans Am and the under hood harness to lights, etc. is original to the 87 IROC. Thanks!
