There is a schematic on the second to last page of the assembly manual…that was what I was referring to when I was telling you to look at the schematic. I’m sorry, I didn’t realize that my explanation wasn’t very useful. Hopefully this graphic will help…
The green pads are ground (aka negative)
The yellow pads are the wipers
The red pads are 5 volts (aka positive)
So you only need 9 wires total sent to the foot controller: one wire for each pot (connected to the 7 wipers), and one ground wire and one 5V wire. The ground pins on all the pots on your controller should all be hooked together…with the ground wire from the board attached to one of those pins. The same is true for the 5V pins…they should all be hooked together and the 5V wire from the board attached to one of those pins.
I hope that helps.
