It's going to be wired just like all the other drop targets. Blue/red wire goes to the same lug on each N.C. switch on each A-B-C-D drop. Then a yellow jumper wire to the N.O. switch on the same drop. Then all the same switch N.O. switches get wired with the brown/yellow wire.

I have added a schematic diagram from the game with the color coded wires shown on the lines. Work backwards. When you see the brown/yellow wire, follow that wire to one side of a switch. The other side has a yellow jumper that goes to the first switch. There should be another lug on that switch and that's where the blue/red wire goes. Since all the A-B-C-D switches are daisy chained, some will have two wires and the last drop target they wire will only have one wire. Just solder it up like the other drops and you will be good.
