Powering Fast Tracks turnouts

[faraway]

I just watched the Bull Frog video on their website, they make it seem pretty easy to power the frog. I guess it doesn't matter which track feed I choose (positive or negative) as long as they're all the same right?

The frog is part of the upper rail when you go straight and part of the lower rail when you diverge. That is what the electric switch has to do with the wire attached to the frog. Connecting it either with the lower or upper rail depending on the position of the turn out. Keep on asking or make a little test with the switch, three connected tracks and hold the wire to the upper or lower track and run an engine over the turnout. You will quickly understand what is right and what is wrong.
