I ordered a kit from this website, but after seeing how easy it is, I figured I would do a write up for those wanting to do this. The kit is nice, everything is included, but this could probably be done with $10 or less in materials from a local auto parts store.
Link to what I bought:
What's included in the kit that you would need:
(1) standard relay
(2) wire taps (or t-taps)
(2) connectors into the t-taps (not sure what they're called)
(4) pieces of 16 gauge (or whatever you want to use)
(1) inline fuse
a few zip ties
Start off with the relay, I mounted it to the same bolt that holds the back of the headlight in place. That done, I ran the ground wire to the small bolt that holds the bumper to the fender. You'll only need about 6" or so from the relay to that bolt. I ran power to the battery with an inline fuse. Run a wire from the relay to the white wire with green stripe that goes into the high beam housing on the back of the headlight. I used a t-tap here. Then from the relay, drop a wire down inside the fender to the driver's side fog light bulb. Throw a t-tap on the driver's side positive to the fog light bulb (I tapped it to the connector that the bulb plugs into). I used a few zip ties to keep things neat.
That's all there is to it. As far as functionality, high beam works with the fogs as well as lows. Even if the fogs are off, when you click the high beams, the fogs kick on as well as high beams. The parking lights and headlights still function as normal.
I don't have any pictures as it was after dark when I finished tonight, but it's really pretty straight forward. The biggest hurdle was just knowing which factory wires to tap into.
