OK, I've messed you up. The Insulfrog switches have plastic frogs and are not power routing. The Electrofrog has a metal frog and is power routing. It's the Electrofrog that you want. I think everyone gets confused by those two names. I wish they'd come up another description.
You don't need any special wiring at all since the power is routed by the points. The only time you'd have to run additional wiring is if you want to supply power to the non-powered route for some reason. In that case, you'd run two leads for the power bus to the first track section beyond the switch.
