Rick, I just changed the photo to make it a little clearer. When the knob is in the off position and the valve on the engine is in the off position as illustrated, just hook up the cable to the control in the dash and secure the outer casing on the clip. It should work properly. A suggestion on the control is to coat it with a small amount of white lithium grease as they get dried out from age. A little lube in the cable helps also. Hope this helps.
