A rodent (squirrel) chewed up the engine wiring on my 2016 Transit Connect with 96k miles. It was repaired at the time but not well enough and I want to improve on it. Spark plug/coil wires were chewed through and others damaged to the point where engine would not run at all. Emergency repair was done at an independent shop. Now one year later another wire broke atop the engine, connected to an unknown sensor. The engine starts and runs but gas mileage is way down, to ~20 mpg.
I would like to either replace the wiring harness section or splice a section in. I would either buy the needed section from Ford or else pull from a parts car at the local Pick-N-Pull.
Which other vehicles would be a suitable donor?
Any tips or tricks would be greatly appreciated. Maybe there is a thread in the archives which would be helpful but I haven't found it, especially re: compatible vehicles. There are not many TC's in the junkyard. I think the Fusion may have the same engine, maybe some Mazda?
