Got the estimate from the dealer, $2800 for the harness and $1000 for the labor. I could have done it my self for about $5, but Ford is recommending the harness and so is the insurance company. Since it is a lease car, I probably have no say in the matter. I would have removed the pins from the connector, soldered new wires to them, then reinstalled them in the connector and spliced and soldered the new wires to the old ones with heat shrink, a little electrical tape and some flex tubing to finish off the repair and called it good.
Have a cat at home, but this happened at work while charging in our shop garage. I normally charge outside, but a fellow jealous coworker complained that the charging cord was a tripping hazard, even though I ran the cord next to a curb. You would have had to intentionally cross between the car and a curb to be able to trip on the cord. The tripping hazard claim was exaggerated! My bosses solution was to charge the car inside the shop.
The rat also chewed a water hose on the expansion tank of our Ford F550 truck.
