Remote Toggle switch for my amplifier(how to)

i just bought a switch from an auto store, and i want to install it to my remote wire so i can toggle my subs power on and off without having to turn on and off my car. what do i do? i was under the impression before i bought the switch, that i would split the remote wire apart, run it through the switch, put it back together, and be on my way, but there is three little metal terminals(i guess), one for power,load, and ground. do i have to get some different type of wire for this, and where do i install them too. if you can go into ultimate detail so i don't miss a beat, that would really help out a lot.do i have to hook a wire to all three, or can i just use my remote wire? thanks.



mine is similar to this one

You can wire it just the way you thought. The terminal for ground just makes the switch light up when it is turned on.

power = the turn on wire from the deck
load = wire going back to turn on amp
