I set up my 500 with the application unlock to run the boom sections on my sprayer. Got everything working fine. Now I want to switch my 500 back to my tillage tractor for spring work and it won't paint when I engage the auto steer like it  use to, it will only paint if I push the coverage button. How do I set it to activate paint with the autosteer engagement for tillage and keep paint activation with the boom sections engagement for spraying?
