The switch goes to the same place your 'key on' power goes. IOW - if the 'key on' is triggering a relay/stinger that turns on your fuse block, that's where you connect the switch.

The first item is a relay. It controls the power on/off to... a fuse box.
The second item is what you're looking for. We made it to answer this exact question.

The switch goes to the relay controlling the second fuse box. That’s how mine works tge club store sells tge switch and has a great diagram of how to wire it.
