Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The primary symptom of a failing switch is the inability to activate or deactivate the system it controls, or intermittent operation. If left unaddressed, this can lead to operational inefficiencies or the inability to perform necessary tasks. Continued use with a faulty switch risks damage to related electrical components or control modules.

Installation Tip

Always disconnect the battery before working on electrical components to prevent short circuits and potential damage. Ensure the electrical connector is clean and securely attached to the new switch assembly.

Service Note

Inspect the wiring harness and connector for the switch assembly for any signs of fraying, corrosion, or loose connections, and test the circuit for proper continuity.
