Picked up a '98 TJ 4.0 a few months ago and have been messing around with things that need to be taken care of. Temperature gauge is running about 110° and then will drop to zero. I did some searching and found out it could probably be the temperature gauge sensor. Went to look for it this morning and I can't find the darn thing. I have a couple of pictures of the engine compartment for your reference. Supposed to be driver's side on the rear, right?
I also found this mysterious wire wrapped up at the firewall. Can you tell me what it is?
