wiring issues

So I was towing my Tacoma through a winter storm on vail pass. My trucks built for the desert so no wheel wells, meaning harnesses are all fully exposed. I got the truck to the desert and noticed the headlights were turned on without me turning the truck on, battery was connected. Then I noticed the temp gauge was -20 Fahrenheit lol. It seems some wires got wet and created continuity between two of the wires that control the specific things I said. If anyone knows of a diagram that could help me track down these wires and get them wrapped in electrical tape asap before something shorts and causes a fire. I’ve got 2 fire extinguishers just in case.

 

Picture of temp gauge for reference outside temp was 42 *F. Gauge reads -20*F.

 

I have recollection (reading this forum) that there are several causes of this temp display discrepancy. Both pertain to moisture, but not outside the vehicle, check your driver side kick panel for moisture; the two reported leak points are a leaky windshield seal and the firewall grommet. Look up high.

 

Hetfield is that you?

 

After the snow melted out temp reset back to normal reading.

 

Just cuz his names James.
