I would make your own by soldering multiple cables together.

We (REV) provided a bag with 8 PWM cables, 2 Y cables, and a 2 wire jumper this year. If you cut the heat shrink tubing off of the Y cables it should be easy to solder in an extra lead from one of the PWM cables cut down. Remember that you don't need to solder the red wire at all as it is not connected to anything in your motor controller anyway.



All that being said, are you using so many motors that your roboRIO has no free ports? As an alternative, you could wire each motor controller individually to the RIO (and if you run out of ports you could use the extra ones broken out from the MXP connector.
