I have a GS2, 2600 screen, and receiver that I use for autosteer on a tractor, as well as some spraying. I would like to install yield monitoring/mapping on my 9600. It currently has nothing. Can anyone give me an idea of what it would take. I know it would take moisture senser, mass sensor and a harness, but would there be anything else? And what kind of sensors, the older ones or the new ones.
