I didn't document it here, you can find it on backroads:

It's a bit of a faff but not too bad, I paid €760 precoded to the car including the combox, there was about 5 hours in the install, repin from the MULF/TCU to the combox plug but it all works, you need the centre trim, which you could cut, it was cheap for the M5 so went new, you have to do a bit of cutting on the center console to resize the CCC controller aperture to suit the CIC controller, it all bolts in otherwise.
Being precoded to the car, you don't necessarily need to adjust to cars Vehicle Order to reflect it but I did.
If you add a mr12volt to that it really brings the car up to date, I would say it's less compromised than the NBT setup I have in the 630.
