Replacing Victron DC to DC charger with Ford 2kW Pro Power Onboard

Re; Replacing my Victron DC to DC charger with my new Ford Truck Pro Power Onboard (2kW, 120V)

Am am preparing to remove my Victron 30A DC to DC charger, and will be installing a “WFCO T57 50Amp Automatic Transfer Switch 125V” in its place.

I have a question related to the installation of this transfer switch. See attached file; Transfer switch diagram question (area is circled in green)

Q; I would like to install a jumper connection between LI & L2 on the ‘tow vehicle’ input line (input to the transfer switch), preferably inside the transfer switch.

Does anyone see any issues with that installation ?

For a complete look at my electrical diagram, I also attached file; Complete Wiring diagram.docx



Any input is appreciated.
