It ought to be included in the kit....
This is proving to be an excellent upgrade to our EVO wheel pilot. - CS 36T. No longer does the AP hunt for a heading. Power consumption down.

will this work with Raymarine ST6002?
The short answer is "maybe". The ST6002 is only one part of four in an autopilot system and is referred to as the "control head" which is the human to machine interface. The tiller angle sensor (M81105) you are asking about is wired to the course computer and provides real time steering angle of the rudder/propulsion unit. The four major components to an autopilot system are 1) course computer, 2) heading sensor, 3) control head, and 4) tiller actuator. Each system has certain nuances dependent upon the application. To know for certain if the M81105 will work with your course computer, you'll need to speak with Raymarine and have all the model and serial numbers available of all 4 components. They can be reached at 800 539 5539.
