Hi Jeff,
Sorry for the delayed response, I was thoroughly enjoying the weekend of football (Go Pack!) and then traveling yesterday.
The footprint is exactly the same. The physical changes you'll see are no aux battery lug, no alt field wire lugs (not needed anymore), and the connector on the back (pass-through) has moved to the front. Testing has revealed that the pass-through wasn't as necessary as we originally thought, and moving it to the front allows for greater flexibility in mounting locations and battery placements (no battery lug on the back either).
Open to questions!
