Hi --

I have a 1989 Camaro IROC that came with pretty much no options at all. I found some power doors (windows, locks, and mirrors) that I would like to install. I found a complete 1990 wiring harness (windows, locks, mirrors) on eBay. Can someone tell me if this 1990 harness is a direct fit for my 1989? From what I've read, I think it should be pretty close. Someone said something about the mirror connections changing the most over the years.

Thanks -- Jeff
