About This Part
Complete floor wiring harness (OE 17566885-00, reference SC2EV-4004300E) for the 2nd-Gen BYD Yuan PLUS Smart Driving 2024-2026. This is the main underfloor wiring loom that routes power and signal along the body floor to the doors, seats and rear modules, terminated with the factory colour-coded connectors and fuse block. The black taped body floor loom mounts inside the cabin under the carpet and is supplied as a full-length assembly, so a chafed or water-damaged section does not force a partial splice repair.

Frequently Asked Questions: OE 17566885-00
Will this floor wiring harness fit my BYD if it is not exactly a Yuan PLUS?
This harness is listed only for the BYD Yuan PLUS, so it is built to match that layout of connectors and fixings. If your car is a close relation or a different trim, do not assume the routing is the same. Look at where the loom sits in the floor of your own car, the side it runs along and the fixings that hold it in place, and compare that against this listing before ordering. A harness built for one layout will not sit right in another, even when the cars look alike.
The number on my old harness does not match, what do I do?
If the number stamped on your old harness does not match the OE number 17566885-00 or the listing number SC2EV-4004300E, do not fit this one. Check the model and the model year shown on your registration document, since wiring layouts change between versions of the same car. Only order once those details line up with what is listed here. Fitting a harness against a mismatched number risks connectors that do not line up or circuits that are wired differently, and low voltage wiring is not something to guess at.
Where does this wiring harness sit on the car?
Inside the car, this harness sits within the floor rather than under the bonnet or the boot. It is made of plastic and finished in black, and carries the low voltage circuits for the Yuan PLUS rather than anything higher voltage. Before you order, open the fitment table on this page and confirm your exact model is listed, since a floor harness is specific to where its connectors and fixings sit within that particular layout.
