Here's a picture of the lever options and functions. On a basic mog you will have the 1-6 stick, the forward and reverse (rear right side and back from the main shift lever with the arrows) and the diff lock knob. That may actually be a lever a bit like a hand brake on some models. I think down is 2x4, half way up 4x4 and right up diffs locked.
The other levers are the cascade box and pto. Ignore them for now. The cascade lever (if fitted) wants to be to the rear for road gears and we can talk you through all that later.
