Frequently Asked Questions: OE 14948570-00
Which side of the car is this harness for?
This is the left side item. It is the left rear door harness, so it runs in the rear door on the left of the car as you sit inside facing forward. The right side equivalent is a separate item carrying its own OE number, and the two are not interchangeable. Before you order, take the door card off, find the marking on the old harness, and check that it reads 14948570-00. If it does not, use the quote route on this page and we will look it up for you.
The number on my old harness is not 14948570-00. Have I got the wrong page?
Probably not. This harness also carries the reference HA6HA-4002300A, so either number can appear on the part itself or on the paperwork that came with it. If your old harness carries that second reference, you are on the right page. If it carries something else again, stop before ordering and send us a photograph of the old harness and its marking through the quote route on this page. We would rather check it against the fitment table than have you fitting the wrong loom.
How soon will this harness reach me?
Allow 8 to 28 days for delivery, counted from your order to your door. Which applies to your order depends on what is available when you place it, so if the timing is tight for a booked repair, ask us to confirm the position on 14948570-00 before you commit the car to the ramp. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
Why is there only one version of this harness to buy?
Because only the Original/Genuine tier exists for this line. BYD is the genuine manufacturer, and no aftermarket maker exists for 14948570-00, so there is no second tier to compare on price. What you see on this page is the genuine door harness in new condition. If you would rather we went looking for an alternative reference before you order, ask through the quote route on this page and say which model and year the car is.
