Insted of connecting the white/black and brown together. I did that and I had problems with the bulbs blowing and fuses blowing. So I check it out and the white/black wire gets 12v when the headlights are on. The brown wire is 12v when the running lights on. So when you put these together it getting way to much volts. So I cut the white/black on and hook the end going to the switch to the brown one and tape the other end off. Works great.
