Ok, had a bit of a break and went out into the garage. The harness does, in fact, go inside of the left front quarter panel. I pulled the liner on that side of the harness doesnt look like any rodents ventured there.
Tracing the harness:
So, starting back over by the battery. I traced the harness down the rad support and across the bottom, then back up the other side.
The harness leg that goes towards the Alternator, a little wire was chewed in half.
Then, at the actual Alternator connector, this wire came from somewhere.
Then continuing on, the two little wires that are going to the AC sensor had some bite marks.
I did see some up by the ABS block. These wires dont seem to be chewed through the actual insulation, but moreso the sheathing. This is the ABS harness side of the connectors and not the actual car harness.
These marks are under the 3 connectors on top of the ABS box. That is the actual car harness.
More sheathing missing on the ABS box side of things. Wire insulation does not appear to be gotten to.
I then followed the main harness through the fender and saw nothing. The harness then splits; one leg goes back to the engine bay for a relay and the horn and the other leg continues on into the car for the underdash fuse block. Nothing seemed to be tampered with on these two legs.
I then had part of the other side of the engine bays harness sitting on the windshield from when I pulled the engine. This is the harness that splits down the AC Compressor, this has some rat-ness.
This is the junction where the harness splits into the injector harness and the AC Compressor harness. I do not see any bare wires here.
Then up to the injectors.....this is pretty self explanatory.
