I'm thinking that you have to have an implement switch but you could possibly trick it into thinking you have one by hooking a jumper wire into the "implement switch" pig tail on the wiring harness.


You'd have to do a bit of messing around to get it setup.   It would require trips in and out of the cab to insert and remove the jumper wire while its asking if the planter is up or down.



What screen are you using?    That may make a difference in whether you have to have the implement switch and it for sure makes a difference in the setup.
