Do you know what this is?

It's just hanging off. Not sure if it isn't applicable to my truck so they left it hanging?

Thanks gang.

 

Outside air temp sensor?

 

Well that's what I figured at first, but from my research ambient temp sensor is a little bulkier and shorter. And I did find one lower. It is mounted to front metal bar:



The one that's dangling freely in the first post has like 2 oval pads on the front. Makes me wonder if it's something more important.

 

Might be the hood latch sensor..
Let me look around and see what I can find..

 

Blue and white/B wires with a white connector..
That's probably what it is..

Hood latch switch
It's part of the hood latch

Being you have an SR, it may not be connected to anything

 

Thank you so much, @1lowlife ! I was worried it had something to do with coolant or radiator. Much appreciated!!
