Frequently Asked Questions: OE 13854774-00
What if the number on my old fuse box does not match 13854774-00?
Take the old part out and read the number stamped or printed on the housing itself before placing an order. This listing covers OE number 13854774-00, also listed as EM2E-3722500A. If your part shows neither of these, hold off ordering and check the fitment table on this page instead, so you are matching against what is actually fitted to the car rather than relying on memory or a description from a manual.
Where does this fuse box actually sit on the car?
This housing is fitted in the engine bay, not inside the cabin, so look for it near the other underbonnet electrics rather than behind a dash panel. If you are trying to confirm you have found the right component before ordering, it also appears under the alternative reference EM2E-3722500A, so checking any markings or documentation against that code is another way to be sure you are looking at the same part.

Delivery to Hong Kong SAR takes 8 to 25 days from your order to your door, depending on the option you choose at checkout. The shipping cost for your country is shown on this page and confirmed at checkout before you pay, and you can follow the parcel with tracking all the way.
