Is there any special wiring that needs to be done with DCC in order to change directions for the engine on a Wye turnout?
Dear tb,
Yes. A wye must be treated like a reverse loop. You can use Item No. 44912, Automatic Reverse Loop Module, to control the polarity change.
Have fun!

You also would need strategically placed pairs of insulated rail joiners (or gaps cut in the rails)
to allow the reverse module and Wye track configuration to work together effectively.
Hope this helps.
Sincerely,

tb-
Just in case the earlier posters misunderstood your question, I'll posit another solution.
The previous answers are excellent if you were asking about constructing a wye, that is, a triangle of tracks such that you can go forward and back resulting in your locomotive running nose first in the opposite direction from the one it was going when it first reached the wye turnout.
If, however, you were simply asking if a wye turnout requires special wiring, perhaps because you've heard other modelers mention the complexity of wyes, you don't need to do anything. You can use a wye turnout like any other turnout and reverse the direction of your locomotive. However, the loco will still be facing the same direction.
A wye turnout is like any other as long as it isn't part of a "wye" (the name for the whole triangular construction). Keep in mind that you can build a wye without using wye turnouts. All you need is three turnouts connected in a wye configuration. Wye turnouts are customarily used because both of their legs deviate rather than only one, making it possible to fit the wye into a smaller footprint.
I hope this is helpful.
