Wow, you got off easy for $600. Eat up enough of the wiring and the car could easily be totaled, due to the labor involved with restringing the wires.
As to your question. The likely answer is yes, BUT, you’d have to build up the harness yourself, or have a shop do it. And if you can’t get the design drawing for the harness, you’d have to buy one to use as a template*. As for being sure that your new wire is not soy-based, I’m not sure how to tell, but there are probably ways to do so.
*although if I were doing it, I’d use the connectors off of the templates with a short amount of wire hanging off (maybe 2 inches, at most) and splice to the non-edible wire at that point. You just need to be sure that your splices are solid and don’t pull apart.
The dealership is seeing more of this problem... It’s common enough that Amazon has a ‘squirrel spray for car wires.
Green on our dime is going to bite these American car companies... Never had this happen with my old Honda.
Thanks for the suggestions...
