I was looking for a wiring diagram for a 1994 Contour and ran across this site. http://www.installdr.com/Harnesses/Ford-Wiring.pdf You'll need Adobe Reader, but i found it pretty helpful. As noted on the page, the wires and the configuration may not be exactly the same as shown, but you can get an idea what goes where if you're trying to install an aftermarket head unit. Hope this helps. Sites like these make life easier for do-it-yourselfers like you and I.
