Anybody install light bars etc?

Bringing this back,
seeing if there are any other options, and also curious if anybody has an idea how to wire in a single light bar (12") to my new truck (2015 3500 duramax).
id like to do mine where it just comes on with the fog lights. I have a wiring harness with all kinds of switches and it has a fuse for protection and all this crap but I would think I could wire it into the fog light pretty easy? I hate electrical so any help would be great
