Adding fogs to base model, is it this easy?

I have a 2014 base model and want to add oem style fogs. I have the wiring behind the fogs but do not have a fog relay or a fog switch on the turn signal stalk. Do I just need to install the lights in the bumper, hook up the light connectors to the wiring already dangling there, install a fog relay, and connect one of the fog relay tabs to the ground under the hood? I want my fogs to come on when I turn my lights to the parking light or headlight positions. Essentially I want them on whenever the tail lights are on (except when braking).
