A different Hitachi 120 question

Got a 120-2 that does the same thing they all do. Intermittent so slow as to be unusable. Discovered a while back that if I jiggle the harness connector where it plugs in to the ECM it will be fine for a while. Sometimes I'd have to give an extra jiggle because the swing brake didn't release or it would go to full swash, but the sweet spot was always there.

Now it's either full swash or no swash, the sweet spot is gone. Looking with a magnifying glass everything looks okay, pins in the ECM...
