Removing WFCO inverter

I have installed a new victron 100/3000 inverter, in the process of removing the stock WFCO.

Looking for input on what to do with the original AC in and out leads going into and out of the WFCO. Should I leave both lines and terminate the romex that is the ac out and leave the 3-prong ac plug that supplies ac to the wfco? Or track it down and disconnect from whatever input on the ac panel that it is wired into? The wfco is wired in with romex, while I ran new 10/3 cable for the Victron.

Thank you in advance!

My old WFCO had a pass through.
I think that means when there is shore power the shore power could pass through to the dedicated inverter receptacles.
If you already installed a new inverter and it works I would remove the old WFCO and terminate both lines.
I would label the terminated lines for the next guy.

I have a Flying Cloud 30FB Bunk. My inverter was in the front storage area. IF I understand the wiring diagram in the owner's manual, there's a direct line from the AC panel (circuit 7) to the inverter. The A/C plug coming from the inverter is plugged into an outlet. The wiring from the outlet goes aft and powers the outlets by the TV and dinette (essentially the outlets powered by the inverter).

I was advised by AM Solar to connect the wiring that went to the inverter to the outlet so it can get power.

I haven't tested it yet because I'm still working on my install.

Hope this helps,

In my trailer 120v out was re-purposed for 12v out and the face plates that were dedicated to inverter power were changed out for USB ports.....
