You don’t need to remove the engine cover. Inside the engine the wires don't touch each other. The approach that I took was to replace the damaged wiring (with a larger gauge to reduce electrical heating) up to where it exits the side cover. I pushed a piece of shrink wrap tubing over each of the wires and into where they pass through the seal in the cover and left the internal portion of wiring alone since they are separated inside the engine. Splice the wires by soldering the ends and using an inline crimp connector.
I also took the oportunity to relocate the regulator itself to the licence plate holder.
