I found the conversion you did on the HOTD. I am trying to convert a Virtua Cop 1 to a HOTD, found a full board set, but I can not find a wiring schematic or pin out on the Virtua Cop to see if they are even compatible and how much I am going to have to rewire. Where did you find a schematic to be able to change the harness to fit the filter board for HOTD?
