Toyota 8-Pin 2.2mm Headlamp / Headlight Waterproof Connector – OEM 7283-1288-40 / 90980-10891 / 1121700822GB002
Direct OEM-specification replacement for the Sumitomo 8-pin waterproof wire harness connector used on headlamp and headlight assemblies across Toyota platforms. Cross-references Sumitomo / Toyota OEM part numbers 7283-1288-40, 90980-10891, and 1121700822GB002. Uses the 2.2mm contact series in black nylon housing with waterproof sealing — a high-density 8-pin connector that consolidates multiple headlight circuits (low beam, high beam, position light, DRL, turn signal, and levelling motor) into a single waterproof harness connection on Toyota’s projector and LED headlight assemblies.
The 8-pin headlamp connector is located at the rear of the headlight assembly, exposed to moisture from the engine bay and heat from the headlight bulbs. A failed connector causes multiple simultaneous headlight circuit faults — depending on which pins have failed, the low beam, high beam, DRL, position light, or turn signal may become inoperative. The 8-pin design is used on Toyota’s integrated headlight assemblies where all lighting functions are controlled through a single connector, making a failed connector particularly disruptive.

Q: My Toyota has multiple headlight faults after a front bumper removal — could it be the connector?
A: Yes. Multiple simultaneous headlight faults are a classic symptom of a failed 8-pin headlamp connector on Toyota vehicles. The connector is frequently damaged during front bumper removal when the headlight assembly is not fully disconnected before the bumper is pulled forward. Inspect the connector before replacing the headlight assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
