Power Relay 12V 40A for BYD Sealion 06 & Song L, OE 12788402-00

Take it in two steps. First, find your model and variant in the fitment table on this page rather than assuming that a marque appearing in the title covers every car wearing the badge. Second, read the rating. This listing is the 12V relay at 40A, and a unit at another rating belongs to a different page even where the two look alike in the hand. The listing names the Sealion 06 and the Song L, so if your car is neither, the table decides it. Ask us on the quote route if it is unclear.

Allow 8 to 25 days for delivery, counted from your order to your door. If your job is booked in, ask us to confirm where OE 12788402-00 stands at the moment, then set the booking around the answer rather than the other way round. 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 12788402-00.

The case is plastic. That describes the body around the relay rather than how it performs, so it mainly matters for handling and storage before the job. Leave the part in its box until it is wanted, since a small part like this is easy to lose once out of its packaging. Nothing about the case identifies the part on its own, so work from the 12V and 40A description on this page when you compare it with the one coming off.

Engine Bay, so it is under the bonnet rather than behind cabin trim. That is worth establishing before any panels come off. This page covers the 12V part at 40A for the Sealion 06 and the Song L, and your own model and variant still need checking against the fitment table here. Where you have more than one similar looking relay in front of you and want certainty before ordering, put OE 12788402-00 to us on the quote route and we will confirm what this part covers.

That is the whole reason the page shows one tier. It says nothing about whether other suppliers produce something comparable. If you are weighing up an alternative that somebody has quoted you, send us its reference through the quote route and we will tell you whether it answers this listing. Any Aftermarket version added later would show on this page in the usual way.
