The adjustment video is not real clear on the reds. There is a metal shell that protects the piston rod. It has two small holes in the top of it. Fully extend the shock, and take a drill bit/awl/welding rod/etc and poke thru the holes and push the rubber bumper that is in there, down to where you can access it at the bottom of the shell with the shock fully extended. It is split rubber and you peal if off. Recompress the shock and with it fully compressed, gently rotate the top while pushing till you feel it drop into the notches in the valving. Turn it CCW gently while holding it compressed till you feel the valve hit the stop. That is full soft. From the factory they will be a half to a full turn from the stop. If you want full stiff (I did on my Winnebago View) turn it full CW till it hits the stop (something like 2½ or three turns) till the valving hits the stop. Now, fully extend the shock, reinstall the bumper stop and install the shock on the vehicle.
Word of caution, even on the soft setting, the shock will be extremely difficult to extend or compress. Took clamping the bottom end mounting in a vise on a HEAVY workbench and pulling for about 5 minutes on full stiff to re-extend it when I was done. I mean serious pulling. Had to stop mid way and take a breather. (NEVER clamp the shell of the shock, always the mounting bolt bushing end.
