focus 2012 towbar electrics

[alz ford]

I have just fitted a towbar to my focus 2012,the problem im having now is after going out at getting the genuine ford wiring and module I cant understand how it fits. the wiring come with instructions but its the green plug that's bothering me, the module has only one green socket but the wiring loom on the car and the wiring harness that came with the towbar both have green plugs on, also where you take the main power from off the fuse box I cant understand where that wire goes also  please help
