trailer wiring

[Pappy]

I am trying to wire my 2006 Expedition for pulling a travel trailer. Anybody know how to connect the seven wire pigtail? I cannot find the connection point in my wiring harness. I know about the brake controller and where it wires, just not the rear end portion. Can somebody help me?
thanks!

The cover on the "plug in" on the Expedition should have the wiring diagram on it .
Or to what each post should be connected
