About Sumitomo automotive connectors
Sumitomo Wiring Systems is one of the world's largest manufacturers of automotive wiring harnesses and connectors, and a primary original-equipment supplier to the Japanese motor industry. Sumitomo connectors are fitted as standard to a vast range of vehicles from Toyota, Honda, Nissan, Mazda, Subaru, Mitsubishi and Suzuki — which makes them one of the most frequently needed connector systems for harness repair and modification.
Common Sumitomo connector applications
Sumitomo connectors are used throughout the vehicle, in both sealed (waterproof) and unsealed forms. The ranges we stock cover connections for:
- Engine management sensors — crankshaft, camshaft, MAP, MAF and temperature sensors
- Fuel injector and ignition coil connectors
- Lambda / oxygen sensor connectors
- Lighting, switch and interior harness connections
- ABS and wheel-speed sensor connections
- General engine-bay and chassis harness housings, terminals and seals
Because Sumitomo connectors are so widely used as original equipment on Japanese vehicles, having the correct housing, terminals and seals to hand is essential for any clean, weatherproof harness repair.
Identifying Sumitomo connectors and part numbers
Sumitomo connector housings are typically identified by a part number in the 6189-xxxx format, with matching terminals and seals carrying their own Sumitomo numbers. If you have the original part number — for example 6189-0033 — that is by far the fastest way to find an exact match: simply enter it into the search bar at the top of the page. If you only have the connector in hand, or the component it plugs into, our team can help identify the correct housing, terminal and seal combination.
