Yep - that's there is to installing it. I seem to recall a screw that needs to be removed on the converter, then plug in the charge wizard. Maybe replace the screw, can't remember.
Consider placement of the control unit too. The cord on the Wizard is maybe 3 feet. On my Landmark, I wanted to place my Wizard controller next to the battery shut-off switch, viewable and accessable just inside one of my exterior doors (above the battery compartment). I had to chop the cord in half, route the wiring and resplice it. Progressive Dynamics approved my method in advance.
Happy charging.
