12-Pin Headlight Wire Harness Connector – OEM 33472-1201 / 33472-1206 / 33482-1201 | Male & Female | LED / AFS

The OEM 33472-1201 / 33472-1206 / 33482-1201 are 12-pin connectors used in LED and AFS headlight assembly harnesses. These Molex part numbers cover the same 12-pin headlight connector family: 33472-1201 and 33472-1206 are female housing variants, and 33482-1201 is the male housing. The 12-pin configuration integrates LED driver, AFS stepper motor, headlight leveling, DRL, turn signal, and CAN bus circuits. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Frequently Asked Questions

Q: What is the difference between 33472-1201 and 33472-1206?
A: Both are 12-pin female housings in the same Molex series. The “-1206” variant has a different locking tab geometry or wire exit angle compared to “-1201”. Match the variant to your original OEM connector housing geometry.

Q: What fault codes indicate a failed headlight connector?
A: Common codes include B-codes for LED driver circuit faults, AFS module communication errors, and headlight leveling motor circuit faults. Multiple simultaneous B-codes from a single headlight are a strong indicator of connector degradation.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
