Special-k, since you posted the video I will ask you, but anyone else feel free to answer if you know. In the shifting video, the interior view one, I see the Range and splitter air lines and switches ( well cant see the range switch but can see the line) but what are the other two lines and switches? I would assume if it was single it would be either an axle range ( 2 speed) or a Diff lock though I am not sure you want to run 2 speeds on a twin screw, though I guess i could still see diff locks working. Anyway any idea what they are?
