Need help switching from Crazy Taxi HR to Out Run 2

I'm having issues in switching over from Crazy Taxi High Roller to Out Run 2.
My CTHR cab works perfect. I believe the I/O board is model number 837-13844

However when I swap in Out Run 2, although the game loads and plays great (automatic transmission), the shifter does not work. Steering, brake, gas, start, test switch, service switch, volume all work perfectly.

When I shift the gear shifter down, Out Run 2 will view this as the "switch view" button. Moving the gear shift "up" has no effect and the "jump button" has no effect.

Another thing to note. In order to get the game to load, I have to go into the service menu and select the cabinet as "upright." If the cabinet is selected as "sit down" then the game will not load. All I get is an error screen that say "Drive board not connected to Main board"

Does anyone know how I can get the shifter to work using the above mentioned I/O board?
Any help would be greatly appreciated.
 
You should check out the tech section on sega-naomi.com

They should have the pinout of the IO board there. That IO board will work fine once you wire it correctly for Outrun 2.

Also, the reason you have to switch it to upright is because OR2 will not boot if the midi drive board does not pass the POST.
