First thing you will notice is that h3 bulbs have one wire, this wire is your positive (+) wire
these bulbs rely on the housing it sits in for a negitive/ground (-).
If you look at the back of the housing for the fog light, you will notice there is a little tab on the bottom of the housing:
All you have to do is attach a female spade conector with a wire to the tab and run it to the negitive wire for the fog light (old pop up motor wire)
and the positive wire from the bulb to the positive wire:
I think this can also be done with the low beam but there is no tab but there is a little screw that i can can get a ring terminal on for a ground.
