Using PWM on a HERO?

[AlexNeedsAName]

So, my team is working on a robot using the CTR Hero. We wanted to use four Victor SPs, but I don't know how to wire it. I can't figure out how many PWM devices the Hero supports. In the user guide it says it supports 3 on page 10, pins 4, 6, 7, 8, and 9 on page 52, and that there are total of 5 on page 75.

I'm more of better at programing than electrical, so I need help. Could we let all the Victors share a ground, and the other cable goes to pins 4, 6, 7, and 8 respectively? Thanks for your help!
