Alright, so it's not working that hot. The air drill only has pins A & B on the weatherpack to the height sensor populated. So I T'd in to A & B on the planter height sensor. The planter height sensor also has C populated and I just let that go straight through on my harness without putting a T in it.

When I went to calibrate the planter height sensor I calibrated the top end first, then put it in the ground and went to calibrate the lower end. The lower end calibration screen said "the height sensor is indicating the height is equal to or higher than the maximum height. check the wiring or re-calibrate".

I can leave the T installed but disconnect the air cart, and it will calibrate fine. I would imagine it would calibrate fine if I were to remove the T as well. Below is how the harness we made is wired up. Any suggestions would be much appreciated. Thanks.
