NEO GEO D BUTTON QUESTION :~~)

[CHUCKY_RUNS_HORROR]

Hello everybody I had a little question for the community... I own a "SEGA BLAST CITY" jamma cabinet and a neo geo one slot motherboard. So three of my six buttons that are on my cabinet work for neo geo but I would like to wire in a "D" button now for players 1 & 2 So I heard that pin 25/c on the jamma harness is what I would need to solder wires to in order to do this. So my question is: If I un~solder the wires that are on pins 25/c now and solder a wire to pin 25 and run it to a button for player one "D" with quick connect and then solder a wire to pin c and run it to a button for player 2 "D" with quick connect would the "D" buttons work and also where would I solder the ground wires to on the jamma harness so the "D" buttons would have power thank all of you guys in advance for being awesome

The SEGA cabinets already have button 4 and 5 wired into the harness. On each player side's AMP connectors, the next 2 wires after button 3 are buttons 4 and 5.

YES I WAS TOLD THIS BEFORE, HOWEVER I WAS NOT ABLE TO GET THE "D" BUTTON TO WORK WITH MY NEO GEO MOTHERBOARD. I EVEN WENT AS FAR AS TO BUY THE OFFICIAL SEGA MADE EXTRA BUTTON LOOM MADE FOR MY BLAST CITY CABINET AND NOTHING

Dunno what to tell you then; that's how all my New Astro Citys work, and that's what the official Blast City manuals say.

Listen I hear you but for whatever reason mine does not work that way. Do you know how I can wire it in myself thou ?? what I really need to know is where do I solder in the ground wire ?

You can daisy-chain ground from any of the other buttons. It's a common ground.
