Yes you will need to open them in the Begin.vi (if you are using the advanced framework, which it sounds like) and then Simply click on the MotorOpen.vi and copy the Robot DefRev and paste it into your robot data.ctl Go to the bundle and expand it by 1 or 2 or w.e, click the name, find the new PWM device and select all elements.

Down in your autonomous expand the Unbundle of the Robot Data In and select the PWM device and "All Elements" and use from there.

Be sure not to delete or copy the existing Controls or Indicators such as Global Data, Robot Data in/Out, Periodic Tasks, etc. Because deleting them will mess up the SubVis (Begin, Teleop, etc) and will require them to be remade into Subvis. Instead simply paste your new Device Refs into each control/indicator point.

If you need more help message me.
