Well, to us, it was a towing equipment install, but to Ford, they need to know what all the wires do in all their vehicles. I knew they would have it somewhere, but no clue where. I would imagine everything is online nowadays, and that's where the 2013 Escape
wiring diagram was. Used to be they would get dealer manuals years ago with complete wiring diagrams, and for all I know, they still do. But they had to know. They're the Ford garage!
Went up to my buddy's garage last night to get new tires
on the truck I'm selling, and was talking with him about it. He couldn't believe Ford didn't have a plug in 7 pin adapter, or at least the wires taped up under the dash (that's the way my truck came, all the wires to hook in a brake controller taped to the top of the steering column). He's not a fan of tying into factory wiring, but of course, I have no choice in the matter. What was Ford thinking?
