This is a new military 24 volt temperature sending unit. This will fit the M38, M38A1, M170, M37 Dodge, and M151 series military jeeps. This has the later style Packard rubber connection. It fits and hooks up to the late USMC Contract M38A1, M37, and M151 series jeeps with no problems.
NOTE: For application on the M38 and early M38A1 with the metal Douglass connectors you will have to use the inner sleeve to make the connection but the outer metal connector will not connect to the rubber outer connector.
