This is a Betts double-contact (D/C) pigtail assembly, a short wiring harness used to connect a tractor or truck's electrical system to a trailer.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It typically plugs into the main receptacle on the back of the cab and provides the necessary wires to power trailer lights (tail, turn, brake) and auxiliary functions. These pigtails are replaced when the original harness becomes corroded, the pins wear out, or the wires get damaged, ensuring a reliable electrical link between the truck and whatever it's towing.
