We tested one of our sensors, and all we needed was the first pwm cable and a single wire from 12 to a 20 amp "custom circuit" breaker. The pwm was plugged into a digital input. (the other ground is redundant according to my meter at the circuit board) The doc is correct about the pulse width. If there is interest I can pull a pic of each width from my tek scope. We had clean response at 5350rpm (891 Hz) on a 10 tooth #35 chain sprocket. The scope was connected to main ground and the signal header on the robot controller.
