Good To Know

Q: How do I know if my reverse switch needs replacing? A: If reverse will not engage, engages intermittently, or the button feels stuck when pressed, the switch is a common culprit. Checking the connector and wiring first can confirm whether the switch itself has failed.

Q: Does this reverse switch plug into the factory harness? A: It is made to replace the original reverse switch on compatible models using part number 4017591, matching the factory connector. Confirm your model year and serial number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
