Ambient Temp Sender location for 2001 Yukon 2500

[Big T]

Where is the temp sender located for the ambient external temp that shows on the rear view mirror for a 2001 Yukon 2500?

I was thinking that it is under the hood someplace.
I’ll be anxious to find out too.
I have often thought of installing one of those onto My truck but have just never braved the trip to the pull and pack.

It's usually behind the grill on the driver's side

Okay, when I have had the grill removed from the truck. Behind there is a two wire plug. That must be what that is for ?

You might get lucky enough to only have to change the mirror and add the sensor. Mine already had the correct wiring from the mirror to the steering column. I had to add the rest

I believe the early gmt800s used the same parts

 

[MrMarty51]

I wonder if that two wire plug behind the grill might be for the fog lamp package ?

Where is it located exactly?

 

[MrMarty51]

Someday I’ll have to check it out.
Go to the pull apart, they are very helpful, personal friends, have them show Me where its all at. Then I’ll pull it all out and charge them for My labor.

IIRC the stock location would close to the driver's side bumper air hole.

Where is it located exactly?

Down low, in front of the cross frame behind the bumper. It ends shy of half way across on the LH side.

That must be it then. Described exactly.
