6189-0134 / 6181-0075 Automotive 8-Pin OBD Distributor Connector — A/F Ratio Sensor, Ignition Module & Transmission Socket for Toyota / Acura
When a faulty connector disrupts your Toyota's A/F ratio sensor signal or Acura's ignition module communication, the result is rough idle, failed emissions tests, and diagnostic codes that won't clear. The 6189-0134 / 6181-0075 8-pin OBD distributor connector is the OEM-specification solution — engineered to restore factory-grade electrical continuity across distributor, sensor, and transmission control circuits in Toyota and Acura vehicles.
Built from PA66 glass-filled nylon housing with tin-plated copper alloy contacts, this connector delivers the vibration resistance, thermal stability, and corrosion protection demanded by under-hood automotive environments. Whether you're repairing a high-mileage harness or fabricating a custom diagnostic adapter, the 6189-0134 / 6181-0075 provides the dimensional accuracy and contact retention force of the original OEM part.

FAQ
Q: Will this connector fit both the 6189-0134 and 6181-0075 positions?
A: Yes. Both part numbers refer to compatible 8-pin connector housings used across Toyota and Acura OBD distributor, A/F sensor, and transmission circuit positions. Verify your vehicle's harness part number before ordering to confirm the correct gender (male plug or female socket).
Q: Are terminals included?
A: Terminal availability depends on the variant selected. Complete kits including OEM-specification crimp terminals are available — check the product options before adding to cart.
Q: Is this connector waterproof?
A: This is an unsealed connector designed for protected under-hood locations. For exposed or high-moisture environments, a sealed waterproof variant is recommended.
Q: What wire gauge is compatible?
A: The contacts are compatible with 0.5–1.25mm² (AWG 20–18) automotive wire, consistent with Toyota and Acura sensor and signal circuit wire gauges.
