the other week i bought an EVTM manual. Electrical and vacuum trouble shooting manual. its OEM ford for tech use, has all the diagrams and some trouble shooting trees. they are year specific. ive already used mine to fix my turn signals (power wire was in the wrong pin of the multi function switch connector) and my power door locks (bad actuators) its just nice to have, so that you know you should have 12 volts to the black and white wire going to the power door locks. also has instructions on how to check components such as all the switches and the multi function switch. if anyone wants to take a look at mine i can let them see it at any meet, or take a few pics.
