Hey guys, I've got an issue with wiring the LED Wiz. I must have printed off an older version of the wiring schematic for the leds...so at first glance and going by the way buttons are wired, I daisy chained all the negatives of my series together. I have 7 buttons per player and I chained all the negatives of these together and have 1 common wire going back to the LED Wiz. Then each positive goes separately back to the numbered terminals on the wiz with a resistor for each in line. After studying this for awhile and looking around, it seems to me that I've done this backwards. It looks like the +5 volt is an output on the wiz and that they seem to be daisy chained together from the positives and the negative goes back to the individual numbers...or is this wrong too?

I don't even have the pc setup inside the cab yet so I can't really test what I have. All I know is that when I hook my daisy chained common ground to the negative of my power supply and connect the individual positive of each to the 5v out on my power supply, it lights up.
So whats going on, do I have everything backwards and if I do is there a way to fix this without having to rewire/re-solder the whole mess?
Thanks for any input, if you need a pic I'll post one
