Hi All,

I am trying to add a pair of fog lights to my 2010 Mini Cooper, but am having some trouble. The dealer wants to charge me $350 to reprogram the computer (rip off imo).

How can I rig the lights to bypass the computer and work off of the switch? I'm looking for a wiring diagram for the 4-post switch (blue, green, brown, grey/red) as well as the 63 12 0 420 296 relay.

I've figured out most of the wires, but don't know the rest. I know that red = +12v, brown = GND, grey/red & grey = computer, and the connections to the fog lamps. I don't know what the blue wires does.

Any help is greatly appreciated!
