I have a Happ dual pedal setup in my cab, using 5k pots interfaced to the PC with an AKI board.
I recently bought a Fanatec ForceShock wheel & pedal setup for the xbox. Obviously I don't want to use the plasticky xbox pedals so I looked into a way of using the Happ pedals for the xbox too.
Basically what I did was remove the wiring & pots from the xbox pedals, and mount the pots to the Happ pedals alongside the standard pots. Luckily there is space for 2 sets of pots without modifying the Happ pedals at all - there are pre-cut holes already. Also luckily the gears on the xbox pots seem to mate nicely with the toothed part in the Happ pedals.
The only problems I had were:
The xbox pots were too short so I bought some replacements of the same value (10k),
The pots I bought were a bit too long so I had to cut them down,
The pots I bought didn't have a flat 'key' so I had to file one in (for locating the gear),
The brake pot in the xbox pedals was mounted to opposite way around so I had to swap the wires on the outer pins of the pot.
It seems to work great
