    I have a 2pin switch, i have a +12v and ground wire going to an LED unit, i want to be able to switch the supply off, can I simply add the switch inline on the +12v wire. So basically, cut the +12v wire and connect one end of each cut to the switch pins? I'm assuming the switch doesnt require ground as all it needs to do is switch on and off

    yes thats correct :)

    just make sure the switch is rated for what ever current the LED unit draws
    the switch should have its rating on the side of it ( most do)
