Trailer tow module question.

[Crinks85]

Hi
I originally posted this in the connect section but havnt had any luck so thought that it may actually be relevant to other new model customs etc.

My model is 2015 transit connect L2 limited

Sorry if this has been asked before but I have search and cannot find what I'm looking for.

I have just fitted was is a genuine ford towbar with all electrics etc, my problem is that I cannot seem to link the module to the vans wiring.
Has anyone here fitted this setup before?
I think I am missing a cable from two seperate plugs, one has 4 wires and the othe has only one, then that should go into a single socket to go into the green section on the module as this has 5 pins inside, does this sound about right?
I am aware that it will probably need programming but why first issue is just to get power to it!
Cheers
