It's going to depend on your preference, but most people will wire the Lippert Electric Trailer Jack # LC285318 after the battery disconnect to avoid having the jack drain the battery. There are people who want the jack to always work though so if this is the case for you then you would just run it straight to the battery and use some ring terminals.

If you want to wire it after the shut off then you can splice it in using a butt connector anywhere after the shut off. In this method you would cut the output wire and strip back the casing, twist up the output wire and jack wire and insert into one end of a butt connector and then the put the other side of the output wire in the other end of the butt connector to restore the connection.

If the output for the shut off runs to a DC distribution panel then you could also just run the jack wire to the panel.

I recommend splicing in after the disconnect so that you never have to worry about it running the battery down while in storage.
