After two tries, the Maverick is back in service.
After the first try, I was able to jiggle the headlight harness and get the headlight to turn on and off without the ignition on. The tape job was also terrible. I undoubtedly would have had issues with battery drain or water intrusion down the road.
I got the service manager and shop foreman involved, showed them my concerns. The shop foreman actually looked annoyed at the work done and told me he would personally redo the the wiring. I asked the service manager for a complimentary oil change for my troubles. You would of thought I asked for a free transmission replacement.
The wiring now looks great, factory fabric tape covered everything. The foreman said there was no ECU wires at issue, so he feels confident that the repair will be a permanent fix. Time will tell. He did change the oil, too.
Peppermint oil sprayed on the wiring, 4 squirrels eliminated. Not much more I can do. I haven't seen a squirrel since getting #4. And the neighborhood fox has been eating well. All the carcases are gone by the next morning.
$933 after tax and the 4th pig tail they needed.
