Fuse Wiring Diagram - Ford Forums

Ok heres the latest issue with my GM. Fixed the TPS the other day and now I have no running lights no headlights no interior lights, no door chime, radio, or clock. The first thing we checked was the fuses. all were good. The next thing we checked was the wiring harness running from the lights to the alt. Burned out at the connectors so we hardwired them together. The lights flicker on and off but wont stay lit. So we check the fuses again and run a meter to see if the pannel is hot. We discovered that the fuse slot that handles the problems I am having is not receiving power. What we have had to do is crossover the wires to get power to the lights etc. So what I need to know is where to trace this wire back. We are going to have to find the short. Sooooooooo if anybody has a wiring diagram handy could ya please provide to me. This has been a very costly car in the past three weeks and I am getting frustrated

As far as finding wiring diagrams, your best bet is to hunt down an EVTM (Electrical & Vacuum Troubleshooting Manual). I don't think you can buy them in brand new form anymore, but they do pop up on eBay from time to time.
