I have a massive Spaghetti of wires under my hood that lead to so many who knows whats. I would like to get rid of this mess but have little direction of what goes where. So i was wondering if anyone had a recomended manual of the electrical workings in the 87 Iroc-z z28?

 

go to helminc.com and buy a shop manual, it has extensive wiring diagrams you wont find anywhere but in a GM shop manual from them.
