Rat or a mouse? Or some other rodents that can climb up there.

I would use rat/ice poison bait and just jump the wires using crimp connectors and heat shrink tubing/non-acidic silicone and gaffers tape wrap.

Stagger the point of the splice if possible, so they are not against each other.
Replacing the harness is $$$$.

Would the crimp connectors cause an issue with the CANBUS? ie load or resistance?

Looking to get some mice bait. Country Australia has a plague at the moment, but i haven't seen any in my local community apart from this wiring smorgasbord under my bonnet!
