You're Fuji 32's worm drive is quite different from a normal steering system. A typical wheel system system has a cable from the wheel to the quadrant on the rudder. If the wheel turns, the cables moves and the quadrant the rudder turn. If the rudder and the quadrant attached to it turn, the cable moves the wheel turns. It goes both ways.
The worm drive on your Fuji 32 is different. Turning the wheel turns a worm gear that moves a lever that turns a disk attached to the rudder shaft. Trying to turn the rudder will try to turn the disk which will push on the lever and that won't be able to move the worm gear. It only goes one way.
Check Edson's website, they have some nice pictures of each system.
Any kind of autopilot that's designed to move the quadrant won't work on a worm gear steering system.
