I strongly suggest you do this with any harness you get from any supplier.
Check all the wiring connections with your originals. If something is wrong, double check with the shop manual.
I have had phone calls about wiper motors not working and the culprit was the wiring in the wrong slots of the bulk head
junction. I have contacted the supplier and made them aware of this but play it safe and take an hour or so to check yours.
You may prevent a serious incident.
