I did this to my '04 with a wire, a switch, and about 15 minutes. If I remember correctly, you find 33 on the LCM, and jump from that to the switch, then back to 34. The lcm has the rear fog jumper, and the switch powers it. I don't have adaptive brake lights, but this mod will work with them. The lights are wired the same, they just need the switch. The fogs will override the adaptive braking lights. Originally I had the jump from 33-34 so that the front fogs where on and so where the back. I have more control over it with the switch. I just put it under the dash down by the foot rest. It is not something that I want to spend $175+ on the correct switch from a left hand drive country.
