I have a base model 2004 Ranger XLT. I mean it's a BASE MODEL, no bells and whistles at all. No power windows, power locks, etc. I'd like to put foglights in the precut holes in the bumper, which are currently filled by a plastic place holder. I saw that all I have to do is remove the place holder, screw in the foglamps, and connect the already installed wire harness.

My question is this: Since I'm adding these foglamps aftermarket, how will they be turned on? I know that they'll have power from the prewired wire harness, but how will they be activated? Will I have to install a switch? If so, how do I go about doing this? Has anybody done this already?
