Are you sure your new rig doesn't have a PD9200 series converter? If it does, the Charge Wizard is already part of it. If you can see the label and there's a picture of Merlin (or Harry Potter in drag) on it, it's got the Charge Wizard. I base this on the pictures of the converters on Progressive Dynamics website. Also, the manual for the unit should be in the owner's info packet that should have been given to you when you took possession.
