A mouse chewed off the wire flush to the temp sensor on the engine block.
Is there a way to order this part without having to order the entire wiring harness?

Does anybody know the years that are compatible with a 1997 ES300 temp sensors?
I want to go to a salvage yard and pick the part, splice the wire and snap in the sensor, but there aren't many retired '97's out there.

 

Yes you can buy the temperature sensor separately, I'm just not sure how badly yours is cut. Could you post a picture for reference?
