I'd be kind of surprised if you got two defective controllers. It's more likely that your PWM cable isn't going in all the way into the victors. It's easy to think that the connector is all the way in when it stops going forward, but the pins aren't inserted. Try wiggling the connector in or bending the pins forwards/backwards just a little to see if it goes in.

If you still have no luck, try looking down the connector with a flashlight and make sure you can see the three holes for the pins to go in. We once received a spike relay where a piece of plastic hadn't been punched out for the pins to fit through and we did it ourselves with scissors.
