I had the same problem you did, same codes and everything. so i just spliced in that pink wire just after the fuse at the fuse block and ran a new wire down to the trans harness and spliced it in. I dont think mine was the igntion switch tho cause when i ohmed the wire from trans to fuse block it read OL which means it was either cut/pinched/frayed.


ok i checked the wire from the ignition switch pin E to the fuse block and it has voltage.

im having trouble with the transmission wire, there are 2 pink wires on the main harness connection on the trans pigtail by the shift linkage side. how do i test them? do i turn the truck on, put it on accessory or leave the key off completly? then do i test from the small pink wire from the ign0 side of the fuse block to this wire and what readings am i looking for, tried it last night but i need a little more information if you dont mind . i really appreciate it. think were on the right track here.
