Toyota 1JZ-GTE / 2JZ-GTE 2-Pin Ignition Coil Connector – OEM 90980-10901 / 90980-10899 / 7283-7023-10
Direct OEM-specification replacement for the Sumitomo 2-pin wire harness connector used on ignition coils across Toyota, Hyundai, and Kia platforms. Cross-references Sumitomo / Toyota OEM part numbers 90980-10901, 90980-10899, 7283-7023-10, 90980-10947, 7282-7028-30, and 7283-7028-30. Uses the 2.2mm contact series in black or grey nylon housing — the standard ignition coil connector on Toyota’s 1JZ-GTE, 2JZ-GTE, and related inline-6 engine platforms, as well as Hyundai Accent 1.6L and Elantra J3 applications.
The 2-pin ignition coil connector on Toyota 1JZ and 2JZ engines is located on the valve cover in a high-heat, high-vibration zone. On the 1JZ-GTE and 2JZ-GTE, the coil connector is exposed to turbocharger heat soak, causing the nylon housing to become brittle and the locking tab to fracture. A failed connector causes a cylinder misfire (P0300–P0306) and rough running. On high-performance and modified 1JZ/2JZ builds, the ignition coil connector is frequently damaged during engine bay work, making a quality replacement essential for reliable ignition.

Q: My 1JZ-GTE has a P0302 misfire on cylinder 2 — could it be the coil connector?
A: Yes. A fractured or corroded 2-pin ignition coil connector is a common cause of cylinder-specific misfires on 1JZ and 2JZ engines. Swap the coil to another cylinder — if the misfire follows the coil, replace the coil. If it stays on cylinder 2, inspect the connector and wiring before replacing the coil.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
