First thing I'd do is spray the crap out of it with PB Blaster or some other penetrating oil a few times and let it soak for a few hours. Then I'd get a pair of vise grips and latch them onto the old sending unit. Once you get the bolt to move just a bit, it will take less effort. Just keep working it out bit by bit and you should get the unit off without major effort.

I'm really surprised that you are getting hung up on this.

hey i want to switch the ild massive gas gauge/idiot light cluster to thee one with the tach, if i just unplug the old one and plug in the new one will the gas gauge and speedo work only? please let me know

 

If you just plug the new one in without changing the sending units, everything will work but oil pressure and water temp. The gas gauge, speedo, tach, and battery voltage will all work. When you change the sending units for the oil pressure and water temp, they will work too.

So I’m starting with a street driven only, garaged most of its life completely stock and basic model 1996 Cherokee. No power anything, no roof rack, and worst of all, idiot lights for oil pressure and coolant temp.
I picked up a new cluster and the details in this thread made the difference when I finally found a parts counter guy who understood the subtlety of gauge sending units but with only one electrical connection.
For anyone who may need this, here’s the part numbers that worked for me.
“Standard T Series” is the brand on the box.

for the oil sender, PS257
for the temp sender, TS334T

Thanks for this resource. I’m
