Pedalpcb.com 3PDT Breakout Board with Output Boost Wiring.

I thought this would be cut and dry to replace the existing footswitch on my Trembling Loon (Tremulous Line clone) by wiring it exactly the same as any other standard Pedalpcb build.

I guess the only thing I can think I'm doing wrong is I didn't wire power to the footswitch board. I assume the extra in/out, grounds and + - are to run it by itself or to wire with other circuits.

In my mind if I can get the volume louder on the Trembling Loon I could finally end my search for a tremolo I love.
