Wiring harness issue

2006 Tundra access cab 6 cyl. Squirrel chewed though some wiring. Mostly the brake level indicator and part of a main. I think I have identified most of what needs to be done and what goes where. Gee whiz it is hard to find details online. Any help appreciated.

 

Ugh, dang vermin! Adhesive lined heatshrink and a soldering iron are going to be your best friends here.

Try to find and match the various wire colors. As long as sections are missing you should able to identify connecting ends. Solder and marine heat shrink will be the best method to reattach. Use a high quality harness wrap and not cheap hardware store electrical tape. Honda sells an anti-rodent harness wrap that contains capsaicin.
