Frequently Asked Questions: OE 14816863-00
My old harness is tagged HA5HA-2106120. Is that the same thing?
They are one harness under two references. This page is built around OE 14816863-00, and HA5HA-2106120 is the other reference for the identical item, so either string will bring you to the right place. Check what is printed on the sleeve or the tag of the harness you are replacing and compare it against both numbers above before you commit. If neither appears anywhere on your old part, send us a photograph of the old part and its label through the enquiry form and we will match it from the fitment data.
When would this harness reach me?
Delivery takes 8 to 28 days from your order to your door. Nothing on this page shortens either number, and we will not quote you a faster route than the one shown. If the car is off the road and the date is tight, say so through the enquiry form before you commit. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What is this busbar harness made of?
This busbar harness is made from metal. On a high voltage busbar harness that is the conducting part of the assembly and not a trim choice, so the item wants careful handling in storage and on the bench. Keep it in its packing until the run is clear and the vehicle has been isolated by somebody qualified to do that. Metal also means the part will not spring back if it is bent to make it reach, so lay it against the old harness for comparison before anything is disturbed.
Whereabouts on the vehicle does this harness run?
This harness runs underbody, so the car has to be raised and the run reached from below. Clip spacing and the exact route across the floor are not given, so use the harness that comes off as the pattern for the one going on. This part fits the BYD Seal 05 and the fitment table on this page shows the matched builds. Anyone working near high voltage cabling should be qualified for it.
Is there a cheaper version of this harness?
Only the Original/Genuine tier exists for this one. BYD is the manufacturer of the part and no Aftermarket version exists, so there is a single version and a single price on this page. On parts where a second source is available, you would see Original/Genuine and Aftermarket together and pick the one you want. Here there is nothing to choose between. If you are sourcing several parts at once and would like alternatives checked across all of them, put it through the enquiry form.
