Plug Housing for Power Double Lock Harnesses
The 4-position count matches a 4-circuit BOM line for a power distribution junction or a sensor/actuator harness.
Terminals and Mating Half
The 177900-1 accepts the Power Double Lock female crimp contacts, which are terminated to the wire before insertion into the housing cavity. The crimp termination gives a gas-tight connection on stranded wire, and the housing's secondary lock (the TPA, or terminal position assurance) is built into the design to confirm each terminal is fully seated.
