I just used this kit to wire my dad's 2012 Transit wagon. His did not have the grommet on the passenger side either. We wound up drilling a hole and installing a grommet to get the wires to the passenger side. We tied the power wire into the rear 12v power point instead of running the wire all the way to the battery. Works great. Hitch install is really simple, wiring is doable but a little more involved.
