With a constant-power-only fuse box, the camera can't tell ignition-on from ignition-off - so Parking Mode either won't trigger properly or risks draining your battery. By giving the camera a true ACC signal, this harness lets it drop into Parking Mode properly the moment you shut the car down and walk away with the keys, then return to normal recording when you start up again.\u003c\/p\u003e\n\u003ch2\u003eHow It Works\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLocate the existing BYD loom that carries a switched (ignition) accessory feed.\u003c\/li\u003e\n\u003cli\u003eUnplug it and connect the T-harness inline - factory plug on one side, your accessory feed passed straight through on the other.\u003c\/li\u003e\n\u003cli\u003eRun the switched output to your dash cam hardwire kit or battery pack.\u003c\/li\u003e\n\u003cli\u003eSet your camera to Parking Mode - it now arms on ignition-off and disarms on ignition-on, automatically.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConfirmed BYD Fitment\u003c\/h2\u003e\n\u003cp\u003eFits all year models of:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBYD Atto 1\u003c\/li\u003e\n\u003cli\u003eBYD Atto 2\u003c\/li\u003e\n\u003cli\u003eBYD Atto 3\u003c\/li\u003e\n\u003cli\u003eBYD Dolphin\u003c\/li\u003e\n\u003cli\u003eBYD Seal\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBYD Sealion 6\u003c\/li\u003e\n\u003cli\u003eBYD Sealion 7\u003c\/li\u003e\n\u003cli\u003eBYD Sealion 8\u003c\/li\u003e\n\u003cli\u003eBYD Shark 6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot compatible:\u003c\/strong\u003e *BYD Sealion 5 - it doesn't feature a compatible 12V socket for this loom in the front console of the vehicle, \u003cem\u003ehowever \u003c\/em\u003ethe rear 12V socket does fit.\u003c\/p\u003e\n\u003ch2\u003eAdd Yours Today\u003c\/h2\u003e\n\u003cp\u003eGet proper, safe Parking Mode in your BYD without butchering the factory wiring.
