Im taking the plunge and building a mame machine. Woodworking will not be a problem...and most of the button wiring to the ipac2 looks easy. I havent seen any documentation/screenshots of how to wire the sanwa jlf to the ipac.
I see you plug in the 5 pin wiring harness to the jfl's pcb...then do those 5 wires, ground, up, down, right, left go to the corresponding places on the ipac2?
