Use Guide

  • Confirm the truck uses a mechanical push control switch before fitting
  • Match the M14X1.5 thread and 30mm spanner size against the old switch before ordering
  • Isolate the battery, remove the failed switch from the rear panel, and install the replacement with the same orientation
  • Test reverse light activation and deactivation when shifting into and out of reverse
  • If the light stays on, check the gear shift linkage and wiring harness for short circuits before condemning the switch
