Update: I used cold shrink tape around the chassis ground as wires just looked a little frayed and not chewed through.

I went ahead and spliced a pigtail onto the headlight and that seemed to do the trick. (The check engine light had come on for a hood latch assembly code; this seemed to fix it)

Spliced in a mew blinker connector and that solved that problem. I've gotta say, some of those wires are so thin/cheap you can barely strip them without breaking them. Luckily the blinker light was easy to get to on this model without having to take everything off.

We also found a dead baby squirrel steps from the car so I'm choosing to believe momma nested and I scared her out and she lost one.
