EDIT - I've solved the problem through trial and error. Windows, locks and mirrors are working like a charm.

I'm in the final phase of installing power mirrors, windows and locks with a set of harnesses from an '88 IROC, into my '92 RS. I'd like to avoid installing the C238 junction box if possible (I do have the box, just in case).

I would like to know how the 2 wiring harness (mirrors and windows/locks) would normally connect to a '92 fusebox, so I can tap into the appropriate lines or plug into the right connector.

I know there's a plug running from the rear of the '92 fuse box for the power option wiring. What does the harness side plug look like and how does the small orange power mirror line fit into the scheme of things?

Any info is much appreciated!
