Ford has one in the accessory catalog for $110, see part number FT1Z-15A416-A. I picked one up from my local dealer the other day, just waiting for my hitch to come in so I can have them both installed together.
I received my wiring kit. There were no instructions, the box points to the dealer only portal. I am sure that I can get it with the brief description on the label; would prefer to see the correct ones. Idid find an older set for Escape.
