Hey Steve! Long time no see
Ya, it was weird. I got so frustrated, I ended up yanking the HLG drivers out and went with LDD's for now. I still want to get it figured out, but with water in the tank I wanted to get some lights up.
Pm me your e-mail and I'll send you the sketch or put it on dropbox or something.
So because I ended up not using the drivers, I didn't need the PWM converter, and thus no longer need the connectors, lol.
