I have the diagram, just gotta find it. I'll get it rounded up tonight or tomorrow AM and see if I can help you out. Gotta go to work now or else I'd do it now.
Go to the library, and look at the automotive manuals. Its not a sure thing, but I have gotten good diagrams and information there. The bigger the city you live in the more books they will have. What sucks is the last time I went they were all checked out. Seems they allow reference books to be checked out now. I have copied the pages I needed on the machine they have.
Jerry - I have done that also. Like you say - the bigger the library the better the chances of getting what you need. The one I wnet to had electrical diagrams of about every car made in the last 20 years.

The heavy gauge yellow wire is pretty much the main feed. The two heavy gauge yellow wires that splice onto the heavy gauge yellow run back to the ignition switch and supplies power for anything that would be a key-on accessory. If you haven't found this connection yet, If I remember correctly it's on the passenger's side in the biggest harness. Let me know if you need to know anything else. I'll keep the diagram by the puter.
