So I went ahead and installed the LED DRL / Fog lights on my r-spec yesterday. I wired mine in so the LED DRL's are on whenever the car is running, and the fog lamps are on whenever the headlights are on. Here is a quick run down of where I wired them in:
First I tapped the factory harness in two places for the "signal" to activate the relays.
For the DRL's; on the passenger side of the car, there is a small fuse box. I opened that fuse box, and on the battery side of the IGN coil fuse (green 20a) I taped the red large red wire.
On the passenger side headlight (Do no use drivers side headlight), there is the pink primary wire (upper right hand corner if you are looking at the plug) I taped that for the signal wire for the fog lights.
I then mounted my relays under the small factory fuse box where you tap the ign. coil fuse wire.
I ran a primary power wire to the battery's positive terminal for the power for both relays. I used a 5a fuse for the DRL, and a 15a fuse for the fogs (You must use a fuse for each circuit.)
I grounded both relay's where under fuse box where the metal bracket that mounts the fuse box goes to the body.
Each fog light has 4 wires, one power for DRL's, one power for fogs, and one ground each. I made a small foot long harness for each fog light and put a 4 wire plug on them. This makes it simple to disconnect the DRL's/fogs when you remove the bumper. This small harness plugs into the fog lights with 4 small female blade contacts.
The body side wires all run to two 4 wire plugs to plug into the fog light harness.
I sleeved all the wires with braided wire loom sleeves, and used heat shrink at all the ends.
Here is a very crude diagram:
