Help me convert Gauntlet Legends from 49way to 8way sticks
Hi,
There have been a few threads on this question already but not in the repair and help forum. Please read this thread quick for reference on background:

Both Demogo and I have Gauntlet Legends dedicated cabs that we would like to convert to use 8way sticks on to be able to swap in other jamma boards. Both of us have changed out the factory medium res monitor for one that supports medium and standard res (his is tri-res).
I can't seem to figure out how to wire up the 8way sticks in this Gauntlet Legends cab. I'd prefer to use the existing cabling rather than add a new harness if it can be avoided so I only have to move one jamma harness to switch games. I know player3/player4 wiring is a separate issue when swapping 4p games so lets just concentrate on getting Gauntlet Legends working with 8way sticks first in this thread.
Here is what I know. The cab comes with all 49way sticks and it appears that Atari re-used the pins on the jamma harness to feed the 49way sticks for player1 and player2. Players 3 and 4 have separate connections to the Vegas IO board just to the left of the jamma connector.
See picture here:

In my cab all these wires are bundled together and zip tied all the way up to the control panel where they break off into 4 white plastic 14wire connectors.
See picture here:

These connectors come apart and are key'd to each player so they can't be hooked up wrong (p1 to p1, etc). The key part involves the missing pin being in a different spot per player.

These plastic connectors then break off to feed the 49way joystick 10wire input and the 4 buttons on the control panel per player.

So now, the base of my question is can we just unhook the plastic connector side going to the control panel, remove the wires from the 49way sticks and buttons, replace the 49ways with 8ways, and get a connector like what is pictured that we could wire to the buttons and 8way sticks? If so, I would think we could wire up all 4 players to the 8way sticks.
Knowing what wire goes where is another question.
Here is a link to the Gauntlet Legends manual link:
http://www.crazykong.com/manuals/GauntletLegends.man.pdf
Look at the wiring section, which shows for me on page 51 of the pdf doc, labelled 3-2 on the bottom of the page. This image shows the jamma edge connector wiring. You can see the player1 and player2 inputs are different from normal 8way setup with directions and buttons.
Now compare that to this Guantlet Dark Legacy Conversion manual:
http://arcarc.xmission.com/PDF_Arcade_Manuals_and_Schematics/Gauntlet Dark Legacy Conversion Kit.pdf
Look at the same edge connector breakout on page 34 of the pdf.
You will see that this manual is for setting up an 8way stick verison of Gauntlet Dark Legacy which is a rom/hd upgrade from the Gauntlet Legends game. Is it safe to assume if we toggle the dips that this would be the new pinout on the jamma harness?
If so and if we could get a connector that fits the white 14wire connector in the control panel now I would think we could try and wire things up.
What do you guys think? Any ideas if this would work, or where I could find the connector/wiring? Or alternate ways of hooking up the 8ways?
Thanks..
