Oh fudge, we just encountered this problem this afternoon after spending an hour trying to make the cabling look neat and orderly only to discover that three of the pwm cables won't properly plug into the sidecar because of this problem.
I also believe we got a batch of bad or wrong pwm cables this year. I notice that the opening that exposes the metal contacts on the wide side is on the opposite side from the pwm connector of the cables we have from prior years. This discrepancy is my tipoff that tells me which kind of cable I'm looking at.
