Mazda 10-Pin Headlight Wire Harness Connector – OEM 6195-0167 / 6195-0164 Direct Fit
Direct OEM-specification replacement for the Mazda 10-pin headlight wire harness connector. Cross-references Sumitomo/Mazda part numbers 6195-0167 and 6195-0164. Used in headlight assemblies across Mazda 3, Mazda 6, CX-5, and related platforms where low beam, high beam, DRL, turn signal, and AFS (adaptive front lighting) circuits are consolidated into a single 10-pin connector.
Mazda headlight connectors are a known failure point, particularly on vehicles where the headlight assembly has been removed for bulb replacement or accident repair. The 10-pin housing locking tab is fragile and fractures easily when the connector is forced or twisted during removal. A partially engaged 10-pin connector causes selective lighting faults — the AFS motor control pins (low current) fail first, producing an AFS warning light while the main beam circuits remain functional. Replacing the connector is the correct repair before condemning the headlight module or AFS actuator.

Q: My Mazda CX-5 AFS warning light is on but headlights work — is it the connector?
A: Yes. AFS fault with functioning low/high beams is a classic symptom of corrosion or partial disengagement on the AFS motor control pins (9–10) in the 10-pin headlight connector. Mazda logs this as C1A00 (AFS actuator circuit fault) or U2516 (lost communication with AFS module). Inspect the connector before replacing the AFS actuator.
Q: What fault codes does a failed Mazda headlight connector cause?
A: Common DTCs include C1A00 (AFS actuator fault), U2516 (AFS communication lost), B2477 (module configuration failure), and lighting-specific codes. The specific code depends on which pin circuit has failed.
Q: Can I replace just the connector without replacing the full headlight harness?
A: Yes. Cut the damaged connector from the existing harness, strip the wires, and crimp or solder the new connector terminals onto the existing wires. No full harness replacement required.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
Q: Is this the same connector used on both left and right headlights?
A: Yes. Mazda uses the same 10-pin connector housing (6195-0167) on both driver and passenger side headlight assemblies. The wire colours differ by side, but the connector housing is identical.
