- Compare The New Harness With The Old One To Ensure Correct Length And Connector Type, Then Plug In Firmly Until Retained.
- Use A Small Amount Of Dielectric Grease On Connector Pins To Reduce Corrosion Risk And Improve Longevity.

- Reconnect The Battery And Test All Rear Lights (Brake, Tail, Turn Signal, Reverse) Before Reassembling Trim.
Most Common Failure Causes
Electrical faults on rear lamp harnesses typically arise from water ingress and corrosion of connector pins, physical damage from impacts or body repairs, abrasion where the harness rubs against metal parts, or brittle insulation due to age and heat cycles. Intermittent contact often appears as flickering lights or lights that work only when the wiring is moved.
