Toyota / Lexus 3-Pin Headlight Switch Wire Harness Connector – OEM 6098-2220 / 90980-11987
Direct OEM-specification replacement for the Sumitomo 3-pin wire harness connector used on headlight switch assemblies across Toyota and Lexus platforms. Cross-references Sumitomo part number 6098-2220 and Toyota OEM number 90980-11987. Uses the 1.0mm contact series in white nylon housing — a non-waterproof interior connector for the headlight switch signal circuit in the steering column or dashboard switch panel.
The 3-pin headlight switch connector on Toyota and Lexus vehicles is located in the steering column switch assembly or dashboard switch panel. It is frequently damaged during steering column disassembly for airbag replacement, clock spring replacement, or steering wheel removal. A damaged connector causes the headlight switch to become inoperative — the headlights cannot be switched between off, parking, and main beam positions. On vehicles with automatic headlights, a failed switch connector can also disable the auto-light function, leaving the vehicle without headlights in low-light conditions.

Q: My Toyota headlights stopped working after a steering column repair — could it be the connector?
A: Yes. The 3-pin headlight switch connector is the most common failure point during steering column disassembly on Toyota and Lexus vehicles. The 1.0mm terminal is easily bent when the connector is pulled without pressing the release tab. Inspect the connector before replacing the headlight switch assembly or combination switch.

A: Yes, terminals are included with all variants.
