This connector is required when replacing the flasher relay as part of an LED upgrade. The 4-pin OEM connector ensures the new LED-compatible relay integrates correctly with Toyota’s combined turn signal and hazard circuit.\u003c\/p\u003e\n\n\u003ch3\u003e2-Pin vs 4-Pin Toyota Flasher Connector – Which Do I Need?\u003c\/h3\u003e\n\u003cp\u003eOlder Toyota models (pre-2000) use a 2-pin flasher relay carrying only power and output — no dedicated hazard input. The 4-pin version integrates the hazard switch circuit, allowing a single relay to control both turn signals and hazard lights. Most Toyota models from 2000 onward use the 4-pin configuration. If your vehicle has a combined turn signal and hazard relay (one unit for both functions), you need the 4-pin connector.\u003c\/p\u003e\n\n\u003ch3\u003eVariant Guide\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale \/ Male 15CM\u003c\/strong\u003e – Plug-side (harness side), bare or pre-wired\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale \/ Female 15CM\u003c\/strong\u003e – Socket-side (relay side), bare or pre-wired\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale+Female 20CM\u003c\/strong\u003e – Both sides pre-wired for harness extension or relay relocation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My Toyota turn signals flash fast on one side only — is it the connector?\u003c\/strong\u003e\u003cbr\u003eA: Fast flashing on one side indicates a bulb failure or high-resistance connection on that circuit. Check the bulbs first, then inspect the flasher connector for corrosion on Pin 3 (L output). A corroded Pin 3 increases circuit resistance, mimicking a bulb-out condition on one side.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Hazard lights work but turn signals don’t — what’s wrong?\u003c\/strong\u003e\u003cbr\u003eA: This is the classic symptom of Pin 4 (HZ) corrosion. The hazard switch input circuit is open, so the relay cannot receive the turn signal command. Replace the connector and clear any stored fault codes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this fit Lexus vehicles?\u003c\/strong\u003e\u003cbr\u003eA: Yes.
