Key Specifications

Why Front Bumper Connectors Fail

Front bumper connectors on Mercedes-Benz and BMW are exposed to road debris, water spray, and physical impact. Terminal corrosion or housing damage causes parking sensor failures (PDC faults), radar module communication errors (ACC/AEB faults), DRL malfunctions, or fog light circuit faults. Replacing the connector restores full front bumper electrical function.

Variant Guide

• Type A Female / A Female 15CM – Type A housing for specific bumper harness position
• Type B Female / B Female 15CM – Type B housing for alternate bumper harness position
• Male / Male 15CM – Plug-side connector

Compare the housing shape and locking tab of your existing OEM bumper connector to select Type A or B.

Installation Steps

1. Disconnect the vehicle battery
2. Remove the front bumper cover to access the harness connector
3. Release the locking tab and unplug the original 8-pin connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reinstall the bumper and verify PDC, radar, DRL, and fog light function
