Toyota 8-Pin 4.8mm Starter / Wiring Harness Unsealed Connector – OEM 90980-11615 / 4F0850-0001
Direct OEM-specification replacement for the Sumitomo 8-pin wire harness connector used on starter motor circuits and main wiring harness junctions across Toyota platforms. Cross-references Sumitomo / Toyota OEM part numbers 90980-11615 and 4F0850-0001. Uses the 4.8mm contact series in white nylon and rubber housing — an unsealed (non-waterproof) interior harness connector used for high-current multi-circuit junctions in the engine bay and cabin harness on Toyota vehicles.
The 8-pin 4.8mm connector is used on multi-circuit harness junctions on Toyota vehicles, including starter motor control circuits and main harness distribution points. A failed connector at a harness junction causes multiple simultaneous electrical faults — the number of affected circuits depends on which pins have failed. On the starter circuit, a failed connector causes a no-start condition. On a main harness junction, a failed connector can cause faults across multiple systems simultaneously, making diagnosis difficult without connector inspection.

Q: How do I confirm this is the correct connector for my Toyota?
A: Cross-reference the OEM part number on your existing connector housing against 90980-11615 or 4F0850-0001. If you cannot read the part number, count the pin cavities (8) and confirm the contact pitch is 4.8mm.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
