un hook the red wire w/black stripe and cap it off cause the white wire w/black stripe will be your new ground.
then connect the red wire for the low beam to the end for the low beam on the bulb and the red for the high beam on the high side of the bulb.
and just repaet it to the other side. but the other side uses a red wire with a yellow stripe.
i just answered two questions with one
as for adding the amber fog light get a set of after market fog lights that are small enough to fit. or you can send me the money for new headlights and materials and i can make you a set.
