Thank you FordForm, with your advise I was able to fix my wiring problem within a thrirty minute period. My 2001 F250 Diesel was blowing the fuse for the instrument cluster/throttle/and overdrive. Removed the steering cowling, iginiton switch, shifter lever, found the rubbing point (contact for the short)on the wiring harness, taped it, problem fixed. (PRICELESS)
