mice ate all kinda wires need help.

Pictures please....

 

Sorry to hear about your mouse problems. I can't help you with the wiring diagram or repairing the damage, but I am currently trying to deal with a mouse infestation in my vehicle (2021 PP). You might want to read some of the stuff I have uploaded there to help prevent this from happening again. I was lucky that mice did not chew on wires or cause obvious serious damage under the hood, but I don't want to give them another chance.

Your various options for getting the wiring diagrams are covered here:

There is probably a network of isolated grounds for important engine sensors using brown wires (different from Toyota's normal color for general grounds, which is white with a black stripe). So if you have a bunch of brown wires damaged, it's possible you might have less of a puzzle there than it could be. But I definitely wouldn't advise making any guesses. Use the diagrams and a meter.

 

How's your insurance; file a claim? Catastrophic rodent damage can total a car, or make you wish it would be totaled.

 

Yep, I agree....our Gen 4's are showing 44 computers when I hook up my OBD2 scanner....holy moly!

We've had good luck, the past 15 years, preventing mice/rats from doing damage in our RV camper by leaving cut up pieces of Irish Spring soap all over the place...they supposedly hate the smell and won't stick around.

 

I had mouse damage on my 2019 Prius. Thankfully Insurance covered($18,000) it under comprehensive as it is an act of nature. The dealer said that if the vehicle was older it probably would have been totaled.

 

Oh my word. That's a lot of damage!
