Installation Notes and Tips

Verify connector style, terminal count, and transmission application before installation. This NS-44 uses a male connector with 5 male bullet terminals, so the vehicle harness and switch indexing should match the original layout. Confirm the exact model-year fitment for Ford Aerostar, Explorer, Ranger, F-150, Bronco, Bronco II, F-250, and Mazda B-Series or Navajo applications before replacing the switch.

For best results, inspect the connector, terminals, and surrounding transmission wiring for corrosion, looseness, or heat damage during service. The part number NS-44 should be matched to the original unit and vehicle configuration, including notes such as 5-pin or transmission-specific applications where listed.
