Great machine and great work you did so far!
The F355 Mega Adapter replaces the I/O board and communicates with BackForceFeeder software for the PC to see the cabinet as a PC wheel with FFB, lights and buttons.

@andre_retrogamer @psyko44 Do you have the Deluxe version of the manual with the wiring diagrams?
If you don't, would you like to track the Clutch and Shifter wires so that I can make a compatible version of the Mega Adapter?

Of course we can see this together! I will send you more photos later and analyze further.
 

Je ne pense pas avoir le manuel :/ a mon prochain passage au box je regarderai dans la borne... sait on jamais. Je vais demander a l ancien proprio ausdi sinon
