How do I wire my fog lights

The toggle switch has a constant 12v a ground and a switch leg, so shoul i make sure the ground is running through the switch? I was over thinking the hell out of this little project, thanks bro im going to wire them up first thing in the morning.

The small plug with only two wires, so i just hook ground to one wire and hot to the other? What about the fog light relay i dont have one in my fuse box? Im making it more complicated than it is figures lol, thank for your help bro you two guys are awesome. I have another question my buddy has a 2000 ram 1500 with a 3.6L v-6 it ran the night he went to look at it to buy and now it wont do anything when turning the key to start, no click nothing but all the lights and buzzers come on until the ignition is in the start possition, should i start checking grounds? Whats the first step you would take?

if the battery voltage is 12.6 volts,and connections are clean and tight,including grounds,suspect ignition switch or the key cylinder that works the ignition switch. i think it's a 3.9L instead of 3.6L,but that don't matter.
