The C5HFH harness adds a dedicated relay and terminal-position assurance (TPA) connectors to provide the correct electrical load and reliable contacts without adding bulky resistors or modifying the vehicle wiring.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this harness fix hyperflashing after LED installation?\u003c\/h3\u003e\n\u003cp\u003eThe harness replaces the factory tail-light connector with a relay-based bypass designed to mimic the original bulb load and timing. That prevents the flasher circuit from detecting a perceived bulb failure and switching to rapid flash.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes integrated relay to regulate current and flash cadence.\u003c\/li\u003e\n  \u003cli\u003eStops fast-flash behavior without extra resistors.\u003c\/li\u003e\n  \u003cli\u003eMaintains proper turn-signal timing for front and rear circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my Corvette C5 and how do I confirm compatibility?\u003c\/h3\u003e\n\u003cp\u003eThis part (C5HFH) is made specifically for Chevrolet Corvette Envy C5 years 1997–2004 and is not compatible with Euro-style taillights.
