    Allen controller question?

    Just a question I have not been able to get answered yet. On Allen's controller, the 12+ in on the 16 pin connector, is that the only place I need to run power too. Or do I run it to the ring terminal that says 12v+ beside it? I made my VGA cable last night and everything seems to be going as planned. I didn't run and mesh wiring, I just connected the two digital gnds to pin 1 on the controller, is this correct? Anyway I really need an answer on this guys so I can tell if this thing is going to work.

    Thanks
