We have had a lot of problems with these connections. So far I have had to replace 3 pwm cables and 1 speed controller. The alignment of the connector is very very difficult, if not impossible. Be careful if you do decide to help the situation by cutting or filing the corners (provide relief) as the plastic may fall into the connector hole. We found some clips that slide in over the connector once they are seated and under the speed controller body - problem is that we have the speed controllers velcro'd down so they won't move around.
Still looking for a better way than hot glue to keep those little buggers from coming out as easily.
