Similar to the last step take another wire that will go to the +12V DC (or whatever you are using). I am using blue wire.

Attach this to a disconnect terminal.

Do the same with another piece of wire (I used brown). This will go to ground.

Attach these to the center poles of the switch.

With my switch it doesn't matter which poles it's attached to, as there is no up and down for the switch. If you don't like it just turn the switch upside down. Otherwise test before installing the switch.

The center poles wiring is a tad confusing. "Similar to the last step take another wire that will go to the +12V DC..." for example as well as connecting to "ground". Also, the instructions are not explicit regarding wiring to the motor. Overall, thanks though.
