As others have pointed out, the Victor talks to you. Download the manual from the IFI website and use it to determine if the Victor is getting the correct commands. As to the PWM cable, a correctly inserted cable will have about 1/8 inch of the connector body showing when it is inserted fully. If the LED is showing correct operation (i.e. full on Red or Green at joystick maximum) then the Victor is happy and operating. That only leaves defects between the motor and the Victor. Look for bad crimps or an open circuit. With the power off a VOM should show a short across the Victor output terminals with a motor connected.
If the LED is not changing or showing no PWM then check you are connected to the RC correct PWM ports and have the PWM inserted correctly at both ends. After that it becomes software.
