Did you get sufficient help on this?
If not, here’s a little more information
on the bottom of the Turnout, there are metal staples..you can attach a wire to them so that the 3 center rails are common..this Turnout was done at the factory..but it’s easy to do yourself.
I use a wire from Cat 5 Telephone/Data cable..it solders easy…and doesn’t cause the Turnout to sit lopsided.
