I fitted to same make as John's above myself, they will work with fly by wire throttle, it's quite time consuming as a DiY project and I spent many hours trying to get the CANBus speed signal and ended up fitting and expensive additional GPS unit & the overall calibration takes several 'road runs'
Having just done 2000+ miles through Holland, Belgium & France and some days 350+ miles to push down to Monaco, the PAS was amazing allowing you to flex your cramped feet on the motorway stretches
If I was fortunate enough to own a CX, I would want PAS again
