Thanks for the pictures...... it helped me tremendously with fabricating a cable from some old left over modular PC power supply cables. I depinned the floppy drive side of a floppy to molex adapter and used those pins as the 4 pins to connect to the board on the topper.
I then took a 4 pin ATX motherboard cable which has the correct connectors to hook up with the IGT top box PSU's wiring harness on each of its ends and cut it in half so I had the two plugs to hook to the machine's PSU.
Next I took a 4 pin molex cable, chopped one end off of it, and soldered the wires from the ATX plugs to the molex cable, being sure to match up with the IGT power harness (orange and black in one pair, red and black in another). The two ATX 4 pin plugs were then plugged into the IGT power harness (keeping in mind that one of the plugs on the wiring harness is a two pin - it will allow you to plug in half of a 4 pin plug into it if you get it orientated correctly)
Lastly, I connected the depinned molex adapter to the newly made cable, and then connected the depinned pins from the floppy connector by inserting them individually into the correct locations on the topper board.
Below is a shot of the machine with the topper and glitter bar running and also my cheat sheet for what color wires went where on the topper board (which ended up being the hardest part - trying to figure out what went where).
Now I need to source a better insert for the topper....... LOL!! Anyone have a Game King insert they'd want to part with? If so, hit me up. ;-)
Thanks again for the help!
