Using a Y-Cable with Int Encoder

Not sure where to put this question. It is cross posted on the “Official Tech Support” forum also.

We want to expand to 12 motors and are thinking about using a Y-cable for the left drive train and another Y-cable for the right drive train. Each side has two motors. I currently have Integrated Encoders on the drive motors. I actually only need one of the integrated encoders in the program so I can get rid of the other three. Can an integrated encoder be used when it is only on one motor while using a Y-cable to power two motors…? How would that work?

Perfectly fine. Just to make everything easier I would configure in the code the motor with the IME so positive power is forward that way positive ticks is forward. Then just flip the other motors 2 wire cable until the motors go the same direction.
