brown is almost always ground....if you have a meter just check the restance of the brn wire to ground. dont forget you will have to take your ml to a dealer to activate the switch on the dash and the green light in the instrument cluster

I took my ML before installing the lamp and they said that they lamp must be installed before they can activate it. So I installed it last night and used the brown as ground and green as hot. I am taking it to the dealer today to have it activated. Thanks for the info.
