The temp sensor uses resistance like the fuel gauge. It's even regulated to 5 volts thru the fuel gauge. See this:

Thanks Bob, I'll check it out but first I would like to find the fuse for it and check that.
OK,
1. Where is the fuse for this?
2. I think I will run a mechanical temp as well
3. I have a 195* stat in now, should I go to 180* being in the desert, but winter here lasts just as long.
Thanks,
Jim

I got it. Some one told me to look for one on JeepForum and I knew I have never seen one on the block (inside), I just thought I was missing something.
Thanks,
I'll keep checking it out. I'm going to print the link and take the dash off and check my wiring, while I'm @ it, I might as well install a mechanical temp gauge. :)
P.S. Where's the BEEF!
Jim-- Here is a suggestion, put that wire that you pulled off of the sender and find that wire at the gauge and take a ohm reading cold and then take a reading while it is hot. You should get 2 different readings. If so your sender is working.---- There's the beef!

Thanks Larry/Bob
OK, installed a new temp sending unit and will add the fluid on Monday (the temp housing was leaking so I re-tapped the holes and installed the correct length bolts from the PO as well as cleaning up the housing/intake).
I do also want to install a mechanical gauge.
Question (just to be sure), the mechanical gauge goes here, correct (pic below).
After I get it completed I will fire it up and see if both gauges work, if not then I will continue to trace it down.

Is this right/wire color on the sender?
