I found this site looking around for a wiring diagram but I think that is only part of my problem. I had a 1991 2.8 engine put into a nice 1982 S-10 body using the 1991 wiring harness and now can't get it started. What I know about it you could put into your ear and never know it's there. My mechanical abilities are pre electronic times. So I will be lurking in the background trying to learn all I can about my problem. This is a great site. Thank you for letting me participate, as I will probably be asking a lot more questions as time goes by.
