1) I install the Toyota factory Fog Light relay in the D46 slot on the top right of the Relay block, and a 15 amp fuse in position 12.

2) I disassemble the wiring harness and wire one side of the switch to D4 pin 3 (Yellow wire into the Headlight switch connector)

3) I wire the other side of the switch to D4 pin 4 (Orange wire). This takes the place of the fancy headlight switch and grounds the coil side of the relay through the dimmer switch.

4) I wire the illumination from the switch to the green wire in the console (Instrument lights).

5) I attach the hot wire from the fog lights to either pin 1 or 2 of B13 in the engine room fuse box.

6) I connect the ground wires from the switch harness and the Foglight harness to ground.

6) Did I miss anything?

That's correct and all of it.

I installed a set on my 09 as above, except I didn't like the included switch or the console location for it, so I installed an LED lighted rocker switch next to the dimmer rheostat. I grabbed the illumination feed right off of the rheostat output (Brown wire in Pin 5 is +, Green wire in pin 2 is -).
