i used; (in parallel with rears, you may need some on rear and front signals?)
Load equalizer for LED; 50 watt, 3 ohm resistors (i tried 6 ohm, but they did not work)
p/n = Dale NH-50
as far as the fogs go, depends on which tails you have, not all euro versions have the fog feature.
you would have to experiment, i am sure the signal is not available on any us harness, would probably have to use some ingenuity such as you did with the front signal wiring.
