Just curious if anyone has ever done this?

I like DRL, but don't like them coming on right when I start the truck (or even in the headlights).
I know how to wire it so the fogs come on when the truck starts, but was just wondering if/how I could wire it so that when I put the truck in drive it would turn on the fog lights automatically.

 

Yeap you could do that

 

Well, it is more of a how to than can I. I figured there is some signal somewhere when the truck is put into drive I could tap into and use for a "on" signal, I just have no idea where to look.
