In the end, we discovered that we were completely setting them wrong - the pins were completed missing the receptacle in the housing, and sliding along the side instead of into the contacts. So we could push them in as firmly as we wanted, and wiggle them forever - they would never be able to touch the contacts. So if you ever have this problem, be careful inserting the PWM's! If you wiggle it before engaging the pins, you can feel the lip of the contacts, and see exactly how easy it is to miss them!
Those things are legendary for disagreeing with PWM cable placement. some days I think they were actually alive and actively dodging the pins!

I'm a FIRST relic of sorts, I remember when we used PBASIC and we got CH Flightsticks in the KoP. In my day we didn't have motorized carts, we pushed our robots uphill, both ways! (Houston 2003!)
