PIAA Fog Lights On Factory Wiring

My truck didn't come with fog lights, but was wired from the factory (no switch in cab). So I have some PIAA fog lights, would I be able to connect those to the factory wiring? Also would I just need to get the OEM relay and switch?

Wiring isnt my forte, so any help would be appreciated.

 

I have the same situation so I used PIAA 510's with an oem foglight switch and Delco relay. I snipped the oem fog light plugs off the oem wiring behind the bumper and spliced in the sockets that came attached to PIAA's wiring harness. Everything but the light plug splicing was plug-n-play. It hasn't blown any fuses yet but I haven't used them much either.

 

The 510s are awesome for fogs, very bright. Its pretty easy to wire up your own switch, relay and fuse.

 

On th oem lights. One of the cords is green and one is white. Which one is the red wire? I bet it's the green one but I wanted to double check.
