Help! A squirrel tried munching on a wire harness that (I think) is linked to the EBCM. I think they can be spliced (see pics). If so, what gauge(s) am I dealing with? Is it possible to get terminated leads? Or should I replace this entire harness? OEM vs. generic auto wiring? Thanks in advance for any advice.

 

I've done a fair bit of harness repair the correct way is to use wire from a donor car. Doesn't have to be wire from the same area of the car or even the same model or year. I remove the wires from the pins and crimp/solder new sections in then solder those to the rest of the harness. I strongly dislike generic wire overall quality is poor.

As for preventing furry creatures from doing that again best of luck.

 

Get a cat or 2...they are even better w mice
I'm not sure if squirrels go into cars or have an appetite for wires but I'm sure mice do
I live pretty much out in the woods and have 2 mountain cats___and no problems 🐈
