Can you identify this plug?

Doing some dash work and freshening, found this plug in the glove box. My glove box light is functioning and the flasher is in view. ? Also, the seatbelt warning light on the dash is functioning. Can anyone identify this?

Yes, that is the harness plug for the ambient temp sensor. Here’s a pic of the wiring, courtesy of @71fast:

Steve, Much appreciated for your quick response.

Is the ambient sensor something that I can buy on NPD or similar? In your opinion, should I proceed with putting the sensor back into service?

It depends on whether you’re trying to restore your car back to the original condition it was in when it was new. That device, along with that red box you see in your glove box, is part of an emission control system on your car. Based on that, you should have your answer.

BTW, if you look in the passenger door pillar, you should see a stainless round sensor. If it’s not there, there is either a hole or a plug in the hole.
