Roland, I hope the picture arrived, I am not great at this electronic stuff.  I grew up in the 1950′s on Olivers that my dad owned without powersteering.   Now, I can drive this with great ease, I have a bad arm and shoulder due to  polio and have to do every thing with one hand and arm. So I appreciate this powersteering system because it allows me to do what ever I need and not become tired.
