mysterious M 38 wire

[wc16]

When we removed the body from my M38 we found a single wire laying in the cowl with the metal tag marked #37, about eight inches long. It has a female capped plug on one end and a male connector on the other end. The plug mount has a hole on each corner for a screw which matches an opening on the passenger side of the fire wall. The plug would face the engine. Vehicle is 4/52. Anyone seen anything like this? thanks. tried the "G". No luck

Note the small plug in the center of this wiring diagram from early M38 Ops & Maint. Manual TM 9-804.



Note, it was discontinued after Sn MC47771. It was an accessory plug receptacle that could be use for a heater, or windshield defroster and etc. The end of the wire was connected to one of the three circuit breakers.

See this military wire number chart and copy it for future reference.
