You'll have to post the picture to the photos area here. I saw
your post on the Digitrax list. You have two options:
1) The stretch from the crossover to the small 'y' could be fed
via an autoreverser
2) The tail of the 'y' could be either fed via an autoreverser,
or fed based on the position of the turnout (i.e. feed it from
either leg, depending on the position of the turnout; that will
require, likely, a relay or other electrical artifice).
I can't tell you which is more appropriate, as I assume your
diagram is part of a larger layout. If the tail of the 'y' in
fact connects elsewhere, then the electrical 'state of affairs'
may be more complicated.

the Atlas turntable; when I lifted the platter off, 2 pins

the pins/springs when you invert the platter to install it.
Anyone run into this issue?
