they should come with instructions if not try wikipedia :)

But basically, disconnect the battery.

Set the meter to "beep" mode (it beeps on a complete circuit)

place one metel bit on an earthing point (a bolt with cables coming off of it) and the other on the end of the leds pcb thats connect tothe car.

If it beeps, thats the earth side.
If both dont beep, then its not wired into the car properly and is switching on the live side which is bad.

am very sure green is the earth mate and the other is the sidelights

if you do get them mixed up it wont blow anything as ive done it on mine, the light just wont light up simple as that :) a mean the worse thing that can happen is that you will blow a fuse :)
