Frequently Asked Questions: OE 14891876-00
This is listed for a lot of models. How do I make sure it fits mine?
It fits a wide spread of vehicles, which is normal for a small interior electrical part shared across a platform. Do not go by the model name on its own. Open the fitment table on this page, match your own variant and build year, then check the OE number 14891876-00 against the marking on the socket you are taking out. If you cannot find your car there, or you cannot get at the old part to read it, use the quote route and send us the vehicle details instead of guessing.
My old socket carries a different reference. Which one is right?
Both are. The alternative reference for this socket is SA3EFU-3725020, and a part that has been in the car since it was built will often carry that marking rather than 14891876-00. Get the trim back far enough to read the moulding properly and write down every character, letters included. Compare what you have with the two references shown here. If it matches neither, photograph what you can see and send it over with your vehicle details so we can check it against the fitment table on this page.
When can I expect this to arrive?
The delivery time is 8 to 25 days, from order to door. If you need it faster than that, say so before you order and we will tell you where it actually stands. Quoting the OE number 14891876-00 saves a round of emails while somebody works out which socket you mean. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What is the socket made from?
The housing is moulded plastic. It takes normal handling perfectly well, but it does not enjoy being levered on with a screwdriver braced against a hard trim edge, and a cracked mounting lug is the usual result of rushing the removal. Use a proper trim tool and support the housing while it comes free, pulling on the body of the part rather than the wiring behind it. If what you have taken out looks nothing like the images on this page, check your variant in the fitment table before fitting the new one.
Where on the car does this sit?
Inside the cabin rather than under the bonnet or beneath the floor, so reaching it is a trim job rather than a ramp job. Expect to release a panel and free the wiring before the socket will come out, and work with the ignition off throughout. Nothing beyond the interior is given for the location, so it will not tell you which panel applies on your particular variant. Confirm your car in the fitment table on this page, and ask through the quote route if you want that checked before you start.
Why is there no second version to choose from?
Only the Original/Genuine part is listed here, made by BYD. No Aftermarket version has been sourced for this socket, so the second tier is empty and the price shown on this page is the only one attached to it. Model specific electrical mouldings of this kind are rarely copied by the independent trade, which is why that tier stays empty. If you know of an alternative reference that suits your car, send it to us through the quote route with the OE number 14891876-00 and we will look into it.
