Good To Know

Q: Why do wires break inside the door boot? A: Repeated opening and closing of the door causes the wires to bend and fatigue over time, eventually leading to broken connections.

Q: Does this harness fit vehicles without rear heated seats? A: This specific harness is configured for models with the rear heated seat option and may contain unused connectors on base models.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
