It's possible that by moving the wires around to test them, it's making contact again however. Have you tried to drive it again? If the short is intermittent, then your best bet is going to be to replace the wire from the fuse to the trans plug since finding the short in the harness with it in the truck will be pretty difficult.

I have half of the wiring out/disconnected. I'll continue to trace the wire back and see which one it is. There are 4 pink wires going to that 10a fuse. I will also check to see how many volts I have there at the fuse.
