I was going to do the same with a TT wheel - sounds like its much the same part. Decided to do a manual swap instead though
The F125 is rotary contacts moving over embedded tracks. Its about 3 hours work to remove and replace on a lift. Probably a bit longer on ramps, but still do-able. The main thing is lifting the gearbox slightly so you can detach the passenger-side gearbox mount. I'll see if I can find the post I made when I did mine
