Yes it screws into the side of the head and has the prob with it.

How can I test the proper function of the 24 V temp. gauge and the temp. sending unit out of vehicle? Have no indication but the cables are ok. Thanks 4 help.

Willys Jeep Parts Tech:
An ohms reader should be able to test the fuel gauge in the tank. A local automotive electrician should have the equipment.
