Honda 8-Pin Lights & Radar Module Wire Harness Connector – Male & Female OEM | Honda Sensing ACC / AEB

This 8-pin connector is used in Honda front radar module and lighting system harnesses. Honda’s Honda Sensing suite — including Adaptive Cruise Control (ACC), Collision Mitigation Braking System (CMBS/AEB), Lane Keeping Assist (LKAS), and Road Departure Mitigation (RDM) — relies on a millimeter-wave radar sensor mounted behind the front grille. The 8-pin connector carries radar signal processing, CAN bus, power, ground, and lighting control circuits. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Radar Calibration After Connector Repair

After any radar harness repair, a radar sensor calibration is required using Honda HDS (Honda Diagnostic System) or compatible scan tool. The calibration procedure requires a flat surface, specific target placement, and correct vehicle ride height.

Frequently Asked Questions

Q: My Honda Sensing warning light is on after a front bumper repair — is this the connector?
A: Yes. Front bumper repairs frequently disturb the radar connector. Inspect the connector and re-seat it before replacing the radar module ($600–$1,500).
