Running wires to the rear harness still didn't fix the problem. So, the tech had to find the root cause. The problem was in one of the Ford harness connectors in the front harness, where a pin was bent in the connector and touching the pin next to it. Must have been that way from day 1. Took something like 9 hours to diagnose, try the work around, then find the root cause. The dealer only charged me 1 hr. He ate the other 8 hrs.
What boggles my mind, is that Ford didn't catch the problem on electrical test.... and that the previous owner never noticed it and never had it fixed while still under warranty. I noticed it first time out and knew it wasn't right.
