Ambient Temperature Gauge and Sensor Install

I get 2 dashes there. They eventually go away. When i first connected it i left the overhead console temp/compass plugged in and got nothing but after a few minutes it clicked that it can supply data to both displays so I unplugged it. I still dont get the numbers but I get the options now (C or F and color of display and I can turn temp reading on/off) where as before I couldn't change it from the off position and there were no other options at all. I have the sensor that came with mirror so maybe thats the issue.

 

I'm confused but, I guess you got a new mirror? Toyo or Gentek? Regardless, use the sensor that came with the mirror. If it displays all the stuff, mirror probably works fine. When I had the Toyo sensor in the Gentek mirror, I got 140F instead of 80F!

Oh, BTW, the Gentek sensor lost it after about 4 months, but they courteously sent me a new one in the mail.

 

Yea bought a gentex 3320S (957) with sensor. But i dont get any temp reading at all.

 

OK, during my install phase, I took THIER sensor, and made a quick connection with the harness provided up top in the cab to verify it worked. So I knew I had a sensor, and anything past that would be a connection issue with existing wiring, or my wiring. Cobble up top first. Then by the fuse box, and process eliminates the location of possible wiring error or failures.

BTW, Gentek had very good online support, and not just during the day. I recall not too late, but answered every one of the few questions I had.

 

Toyota Tacoma 2015. I don't have inside harness for temperature sensor. But have sensor outside behind grill. This sensor using only for measurements temperature or for A/C unit as well? Any chance added factory harness inside for plug and play Mirror with temperature display?

 

AC unit? If you have the outside plug I'm 99% sure you will have the overhead one in there. My truck is the base model and was pre-wired for everything.
