So Many Questions???

[Aron0980]

I have a few questions about the electrical systems for the robot. I've been looking all over FIRST's website for the rules with no luck and I'd like to get this all squared away before kickoff.

Can we use a multiple wire cable with connectors on both ends(Ex. D-Sub) to connect say multiple encoders on a shooter down to the control board. Instead of having to run those tinyyyyyy little wires down through a bundle. Any ideas or examples of what you all have used in the past that is legal?

What are the rules of busing? With the motor controllers, can you run one wire from the GND plug of a single PWM output to more than one GND pin of a VEX Victor 884 or 888 motor controller. Looking in the schematic for the Digital Sidecar all the third pins are connected to ground on each plug. Would FIRST accept that?

I'm sure I'll have more questions as they pop up but those have been the two bothering me recently.
