I'll chime in a bit and try to help you! if you have the simplest MFSW then it uses only one Lin bus (pin 17). if there are cruise control buttons on the steering wheel, then the steering wheel works on another Lin bus (terminal 36), even the signal starts working on the Lin bus. thus, when installing a steering wheel with CC, it is the steering wheel that needs to be moved to pin 36! also with CC on the steering wheel, you need to move pin 26 or 29 to pin 11, isolate the freed wire from pin 11! to activate Lin on pin 36, block coding 09, byte 29 bit 6 is required.
