TJ: wire in back of enine compartment not used
 

Hi on the back of my 98 TJ 4banger theres a wire that looks like its a sensor or some sort thats not being used. Its sort of just taped up together. I was wondering what it was.

If it's small with two blue wires, it's for the AC.

my jeep does have a/c. so why would it not be used.

Not sure what you are looking at. My 2000 TJ has a small connector with two blue wires--maybe 18-22 gauge, plugged into the top of the AC can. This allows the AC to shut down if the system is empty, saving the system from damage. This is on the passenger side, and is about 5/8" across. I have only one other connector, mounted to the center of the fire-wall, about two inches wide. This is part of the main wiring harness.
