You can hopefully repair the mess or buy a new wiring harness. Either way, it may take a couple of hrs of labor (probably a day for me) to complete the job. That sucks though. I will look to see about the harness number if you do not already have that info.

Kind of depends on what the little varmints chewed through. Different wires go to different components, although most are repair-able. It will mostly just cost you "time." Get the schematic and a good soldering gun. Be patient; I cannot emphasize this enough. Do NOT go the wire nut or butt connector "quick fix" route. Your friends and family don't want to get a call because you're stranded somewhere....or worse yet, because you had an electrical fire under your gas tank.
