Your best bet is to get a copy of the manufacturer's service manual. EBay is good place to look. Look for a seller who goes by the name of "blackhatauctions". I bought a lot of Ford manuals for my school from them.
In this case it's not actually the service manual you need. You need the "EVTM" manual. That is their "Electrical and Vacuum Troubleshooting Manual". It will have 50 - 100 pages of wiring diagrams.
You can also buy a subscription for just your car from an online company that the repair shops subscribe to. One is "AllData". For better wiring diagrams, go to the top of this page and click on "Manuals". That will take you to the "Mitchel On-Demand site where you can also buy a subscription for your car.
What kind of problem are you trying to solve?
