Prerunner no temp gauge, is wiring there without OEM package?

Hello! I have an 06 SR5 Prerunner and I am interested in purchasing an aftermarket rear view mirror with an ambient temperature gauge. My question is, does the wiring exist for the temperature gauge or rear view mirror back up cam, just tucked away inside the overhead panel since my package didn't include it from factory? Thanks!

 

Just open it up n see if you have it there. Contact Bob Mirrors and he will set you up with what you need with instructions. My 2007 Prerunner had nothing there. I had to add the grill sensor, very easy.

 

Pop the hood.
See if you have a connector where the temperature sensor is.
If you don’t have the connector, the chances are you don’t have the wiring.
If you do, you probably do.

You’ll have to zoom in to see the sensor.

 

@John43 @TnShooter thank you for the tips, that should be enough to get me going!
