Hi, this item is to fit to a Transit custom years 2012 to 2023. 7 pin trailer plug on one end, the other has a rectangular plug, the rectangular plug connects to another plug underneath the rear of the van. Giving you trailer electrics without having to cut into the vehicles wiring. 

Made by a local auto electrician with 20 years experience for a fraction of the price of the ford item.

Please note for this to work your van needs to have the trailer module fitted at the passengers side front door, this sends powrt to the plug underneath the van. some vans have it as standard, some don't so its best to check.

Thanks for looking

Tom
