1990 XLT nightmare
Well, I only brought it on myself...I was bragging up my sons F150 to my Dad while we were in Tuscon, and the first day were back, it craps the bed. Ignition switch came apart (literally, in pieces!), so I went and put in a new one...but I'm getting nothing to the ignition circuit or the fuel circuit. Head lights illuminate, brake lights work, PDLs work, but no interior lights, warning lights, nothing. Here's the catch: at sometime in the distant past, it had a severe short circuit. The previous owner, instead of fixing it correctly, installed some Bubba work around, with a push button switch on the side of the dash to run the starter. THAT works, but no bang-bang, runny-runny. Does anyone have a wiring diagram for behind the dash? I have the engine diagram (Haynes manual), but nothing for the underdash harness.
