Frequently Asked Questions: OE 12748392-00
The harness in my car is labelled SCEG-2105300. Is that this one?
It is. This harness carries two references. One is the OE number 12748392-00 and the other is SCEG-2105300, and both describe the same sub-assembly. Read the whole string rather than the leading block, since the two references look nothing alike at first glance and it is easy to conclude you are on the wrong page. If the marking has gone or what you can read matches neither of ours, do not order on a guess. Send us the details with your BYD Yuan Pro information through the quote route on this page.
What is the timescale on this harness?
Delivery time is confirmed with your quote. Plan the work at the later end of that window rather than the earlier. If the schedule is tight at your end, raise it through the quote route on this page before the order is placed. The shipping cost is confirmed with your quote. Before you order, check the number on your old part against OE 12748392-00.
How is a package this long handled in delivery?
The packed length is what governs this one. The packaging details are shown on this page. Expect it to arrive on a service that needs somebody to take it in, and make sure whoever receives it has somewhere to lay it flat rather than propping it in a corner. If access at your address is awkward, tell us through the quote route on this page before ordering.
What is this harness made of?
The material for this harness sub-assembly is Plastic. That is what you see and handle from the outside. Treat it as something to unpack carefully rather than pull out of the box. Keep the old high voltage power distribution harness sub assembly until the new one is fitted, in case the two need comparing.
Where does this harness run on the car?
This harness sits underbody, so it runs beneath the floor of the car and is reached with the car raised rather than through the cabin. Anything routed down there picks up road dirt, and the fixing points need locating before the old one can come out. This is high voltage cabling, so the vehicle must be made safe first by someone qualified to do that. Confirm the OE number 12748392-00 against what is fitted, then check your model in the fitment table on this page.
Why is there only one option for this part?
There is one version of this harness on the page, the Original/Genuine part from BYD. No Aftermarket equivalent exists for 12748392-00, so no second tier is shown. That is simply what is available for this reference. High voltage sub-assemblies are ordered by reference rather than by resemblance, so if the part you need looks close to this one without being it, use the quote route on this page with the number from your own car and the model detail, and we will check what can be supplied.
