Frequently Asked Questions: OE 14758701-00
The number on my old part does not match 14758701-00, what now?
Do not fit it on the strength of the number alone. Check the side it sits on in the engine bay, its position and the fixings holding it in place against what is currently on your car. The engine bay location and fitting points need to line up before you order, since a mismatched number can still mean the wrong harness for your build. If anything about the side or fixings does not match, use the fitment table on this page to confirm before you buy.
Is this the same part as HA5H-4001010?
Yes. This harness is also listed under the reference HA5H-4001010, so if you have seen that code on a supplier site or in a workshop manual, it points to the same item as OE number 14758701-00 here. When you are matching parts across different listings or documents, use whichever number is printed on the part you are holding to confirm you have the right one before ordering, rather than relying on memory of a code seen elsewhere.
