Vehicle is an 02 Durango 5.9 SLT 4x4. Ive been hunting down all of my ground points to check for loose connections because of problems Ive been having and found this plug not connected to anything. Ive looked all over the area and cannot see where it should go. Thanks for your help.

 

i have the same thing on my 98 5.9l slt. i believe i heard somewhere that its an outside temperature harness. not positive though

 

it could be an outside air temp sensor, it was not a standard part on all vehicles so, however im sure that the plug would still be there even if you dont have the sensor

 

I have that plug too... 2002 SLT 5.9L AWD

 

Might have been for a different sized motor. If everyone else's in the 5.9L is unplugged then leave it.

 

Thanks for the help everyone!

 

Could it have come off the air box?

 

Im gonna have to take a look in the morning.

 

Not that I know of.
