From your picture, it looks as if you don't have your PWM cables connected. Also, if you have connected them, make sure they are plugged in properly so that the white wire is plugged into the SIG pin and the black wire is plugged into the black pin. Same with on the Victor; the white wire should be facing the outside of the Victor. I've also found that sometimes when you insert the plug into the hole, it does not make contact, and therefore, does not work. The easiest way to try to connect the PWM to the Victor is while the Victor and RC is on (but please be careful not to touch the power wires o the left).
Here is the PDF for the Victor:
