Guage Temp sending unit help
So I own two cherokees, an 88 laredo with all the bells and whistles and just bought an 89 base with a perfect body and interior with a 4.0 with only 150k on it, but my dilema I swapped the guage cluster so I could go from 2 guages to 6 and swapped in the oil pressure sending unit and the temp sensor in the radiator and the only guage that isnt working is the temp . . . Did I miss a temp sensor? The guage worked in the other jeep

The temp SENDER is at the driver's side rear of the head.

I think you should have three. One for the ECU (low driver's side of the block), another for the gauge (rear driver's side up high), a third for the electric radiator fan (in the radiator tank).
