Compared With the Alternatives
| JAC dealer original switch | Same fitment and function at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging |
|---|---|
| Universal switch with adjustable thread | The M18*1.5 thread and 27mm spanner size match the original, while a universal switch may require thread adapters and lacks the exact fit |
| Used or reclaimed switch | New units carry a 12 month warranty from B/L date; reclaimed stock carries none |
Use Guide

- Match the M18*1.5 thread and 27mm spanner size against the old switch before ordering
- Isolate the battery, remove the failed switch from the rear panel, and install the replacement in the same orientation
- Test the reversing lights in reverse gear and confirm they activate and deactivate correctly
- If the lights remain on or fail to activate, check the gear shift linkage and wiring harness before condemning the switch
