Hyundai / Kia 16-Pin Central Control Unit Wire Harness Connector – Male & Female OEM | BCM / Body Control
This 16-pin connector is used in Hyundai and Kia central control unit (CCU) and Body Control Module (BCM) harnesses. The BCM is the central hub for body electrical functions — central locking, windows, lighting, wipers, horn, and interior electronics. The 16-pin configuration consolidates multiple BCM input and output circuits. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Frequently Asked Questions
Q: My Hyundai/Kia has multiple body electrical faults after water ingress — is this the connector?
A: Yes. Water ingress into the BCM connector causes multiple simultaneous body electrical faults as the water bridges adjacent pins. Dry the connector thoroughly, clean with electrical contact cleaner, and replace if corrosion is visible on the pins.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
