Hi all, i bought a daytona cabinet twin without any pcb, only with monitor chasis and control panel (gear and steering Wheel and motors), i am thinkin use my pc steering Wheel hacked with the daytona, but i don t know how to resolve the issue of the 3 switches of the  4 gear shift using a logitech steering wheel or other like this. Maybe anyone can help me.

skip to the last couple posts for the best solution:

Easiest method would be just to couple that with a keyboard encoder rather than trying to hack it into a Logitech wheel.
Just about all games and emulators support both a controller and a keyboard simultaneously.  (I can't think of any that don't)

It also depends on which Logitech wheel you're using.
The Momo I hacked posted as different buttons depending on which of two ground wires were used.

I figured out what was needed to replace a G27 shifter with regular switches in this thread, but never got around to actually building it.

EDIT:  This should be added to the driving cab info thread.  I'll try to do a better job of explaining the options when I get around to adding it there.

"FYI, the above is not the correct pinout. 

See here for basic pinout from chip data sheet.

I haven't personally done this, but I would assume the one at the end is correct.
I'd trust the manufacturer's datasheet or at least start out believing it most likely to be correct.
