Its 4.80mm pitch gives enough spacing to handle moderate power levels while keeping the connector compact for tight harness routing. The locking ramp fastening type holds the mating halves together under vibration — a half-turn loose isn't a worry here; the ramp clicks home and stays put.
The housing is free-hanging (in-line), meaning it terminates a cable and mates to a panel-mount or another in-line half — no PCB footprint on this side. The black PA66 (Nylon 6/6) housing handles underhood temperatures and resists common automotive fluids.
