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.
