DC Controller Ground Cable for BYD Destroyer 05 & Qin PLUS, OE 12946732-00

Cables of this sort are often catalogued twice. Ours is listed as OE number 12946732-00 and also known as HA2HC-4002918, so a quote carrying either reference is pointing at the same ground cable. The marking is usually on a label or a sleeve near one terminal rather than on the lead itself, so check both ends of the old one. If neither number appears, do not order against the length or the look of it. Send us what you can read together with a photograph of the old part and its label and we will confirm which cable it is.

Delivery takes 8 to 25 days from your order to your door. Order against the OE number so the right reference is picked, and if you need to know where things stand, quote that same number when you contact us instead of the part description. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12946732-00.

The material for this cable is metal, which is what you would want in a ground path. The practical point is at the ends. A ground connection depends on clean, tight metal to metal contact, so the stud and the surface it lands on should be clean before the new cable goes on. Do not paint or coat the mating faces. No torque figure or routing detail is given, so use the vehicle manufacturer's instructions for tightening and for how the cable should be clipped along its run.

This cable mounts in the engine bay, running to the DC controller housing. Access is from above, but the area involves high voltage equipment, so the vehicle must be made safe by someone trained to do it before anything is disconnected. That is not a job to start simply because the cable itself looks straightforward. Take a photograph of how the old one is routed and where it is clipped before you remove it, since only the mounting position is given here, not the route the cable takes on your car.

This cable is offered in one version only. The Original/Genuine listing carries the BYD name, and no Aftermarket equivalent is catalogued against OE number 12946732-00, so a single tier appears on this page. Ground cables are made to a length and a terminal arrangement that suit one installation, so a generic substitute is rarely a straight swap. If you are weighing up an alternative from elsewhere, compare the OE number instead of the description, and ask us through the quote route if you want the reference checked.
