Adapting a JD Greenstar ready tractor for AOG

[BGunics]

I succeeded with the 2k/1k resistor combo (some AIO comes with 12k/6k which made the signal weak…)
Also as @Pat suggested I removed the C3 from the pressure input (probably not necessary)

You can add a voltage divider from through hole resistors to the back of the board.

As for the firmware it’s here:

TeensyModules/V4.1/Firmware/Autosteer_gps_teensy_v4_1_JDautotracKickOff.ino.hex

And I’d probably buy the delphi 2 pin connectors (2 grey 1 black) wire everything to the valve and make the terminators as I described it here:

How to attach to new john deere steering column

If it’s a JD FEMA system then there’s a green / yellow wire coming from the steering column it’s pwm signal but we can use it for disengage. I just figured out the props for terminating the valves: connectors (2 grey + 1 black) 829-12084669 (left/right get 2) 829-12066016 (lock) 588-40F15RE (lock) 807-DC780R-564K (left / right so get 2) As for the AIO PCB: I had to remove the C3 from the pressure sense line. Also the voltage divider better be 2k / 4k or smaller instead of the 6 / 12k f…
