Kenworth 521 (SMRS Re-work) v2.2 for 1.47+

Update 2.2:

 - Fixed steering wheel position

 - Added Cummins Big Cam engines + sound

Note: Back up previous 2.0 version if you like default cables so you can go back then to them if ypu dont like these new ones.

Known issue: Inside openable windows not working, for outside working fine. If anyone want to help with these openable windows then you're welcome! :)

IMPORTANT NOTE: If you used ReneNate's similar truck mod before then sell it and remove before you enable this mod.
