Your post is not exactly clear. You have a set of three way switches
controlling two hall lights, but each of the switches are in double gang
boxes. Are there not switches already in these two gang boxes? Assuming you
have two boxes with empty spaces for switches: you want to install switches
at each box to control the porch lights. Assuming you want to set up three
way switches, so the porch lights will operate from either location, you
need a three wire cable run between the switches, you need a feed, which you
may or may not have in either of these boxes, and you need a cable going
from either box to the porch lights you want to control

I have a 2-way switch in my hallway. One at the front door and one at
the back door, on the same circiut. They control 2 hallway lights, and
work perfectly. I have a double switch box installed in both places.
I am wanting to install a single switch into each box, to control the
porch lights. I need to jump the power from the 2-way circuit switch,
to the single switches.
How is this done (safely, by code) ? There are 2 black wires, 1 white,
and one ground connected on the double switch. I have 1 black, and 1
white on the porch light. The ground going to the outside base.

I have been reading other posts, and haven't seen anything to cover
this.
Also, if you are just going to call me an idiot, save your time, I
think your just an ass too. LOL. ( I've seen alot of that on here)
If you can help, please do. I had my dad explain it, and I did it like
he said, but it ain't working. ( He is a licensed electrician... don't
tell I'm asking someone else..lol)
He had me jump a wire from the bottom black screw, to the positive, and
connect the extra white to the negitive. I have tried this from both
black wires, and still have no power to the porch. HELP PLEASE. I do
know how to follow directions.
