I have seen two posts with people posting pictures with this counter in the Pachislos: !BQOlUv!BWk~$(KGrHgoOKj8EjlLmUE61BJ3v3HJCeQ~~_12.JPG

Both machines have been similar to the machine I would like to install one into. I have both a derby boy and Hokuto no ken (from 2003). They both share the same relay board. I have read their posts and I am a little stuck. I do not have a harness so I would be soldering directly to the status board itself. I am a little confused on what to do with the wires. Heres where I am at:

Red - 12v - can find easily in the machine - I believe the florecent lights use 12v.

That leaves the black, blue and yellow. Here is a diagram I have modified to show my interests. I am only looking to measure coins in and out.
Original: status board.jpg

It reads "To use these signals you must supply and external voltage of 24v and ground" So does that mean I wire 24v from my transformer to the 24v reset pins? Not sure if thats right.

Heres what I would speculate I would need to do with the extra wires:

Any input would be appreciated! Thank you!
