er, i don't have a diagram, but you don't want to wire from the switch directly into the lights. the lights will require too many amps to run thru a switch. You'll need to have the switch run a 12volt relay and the lights will wire into the relay.
the relay is basically a magnetic contactor that closes when the switch is turned on. it takes nearly zero amps.
You can use a continuity tester to test the different terminals on the switch as you turn the switch . this way you can figure out which terminals you need to use.
