So, I do have conneted the groud and sense low together with a jumper in the pcb
See the kaupoi pcbv4 schematic :
From the pcb the wiring continues with three wires to was. In the wire harness, where this Y cable is I have divedied the signal only to go to different ecu in tractor, so the automatic front diff lock ability continues to work. This is just specific to these cnh machines, not related to ago.
You are correct, gnd should be connected from WAS to PCB was low, and you should use differential mode, if WAS is powered from tractor ecu.
I ought to do so on the T6, but as mentioned above it works anyway.
FiveFinnishFarmers power 5v and gnd from PCB, so differential mode is not necessary. Also because he made the Y cable opposite as me, and only connected signal to tractor ecu.
And to make clear : when I some day are going to redo the wiring on the T6, then I will certainly follow FiveFinnishFarmers wiring 
@FiveFinnishFarmers @Larsvest your notes and info for installation in Case/New Holland was very good and just worked easy as including the A0 pressure sensor in AgOpen 
.
What GPS type are you both using? Where is your Antenna mounted? And do you have the saved vehicle file from AgOpen?
Thanks
Happy you could make it work. I am using a F9p with antenna ann-mb-00, placed on the original GPS metal plate on tractor roof. I don’t have the files here, and they would also still be ver 4
I have connected everything, but not the pin Press sensor signal, I don’t understand what is it?
Pin 19 29 39
Can you explain me?
It is simply an analog sensor that measures the pressure in orbitrol that is created by moving the steering wheel. The connection is similar to WAS connection, except it is 5V for the pressure sensor.
Pin 29 is 5V
Pin 39 is ground
Pin 19 is 0-5V analog signal for arduino.
So basically what the sensor does is that it measures wheter you try to turn the steering wheel and how strongly you turn it. It does not matter wheter automated is engaged or not.
Nice thing about it being analog is that you can adjust the sensitivity (the steering force required) to switch auto steer off.
I’v done it with that little transistor and potentiometer thing for adjustment and connected it to remote pin in the pcb.
I do not recommend this as it is not the best way of doing it anymore.
What you should do is to connect the signal directly to arduino and use the build-in feature of AOG to adjust the sensitivity for auto steer disengagement.
Unfortunately, I’m not fully familiar with this connection as I don’t have it (but I will update to this setup). Maybe @Hansdampf can confirm the connection as he writes about it in his earlier post:
Edit:
There’s an earlyer discussion about this on larsvest topic
Ok. I understand.
I don’t need to connect every pin with my pcb. Only A0 with aog 5.2.
I don’t know why but i have connected every other pins and autoguidance don’t work.
I will tell you my connections pins.
Is there something to configure? In AFS monitor? Or fuse or relay?
You do need to connect the 5V and ground for pressure sensor.
Does the system do anything? Is the arrow/status icon green in your AOG display when autosteer is on?
Yes. Aog works.
Everything green.
I have tested my connections with multimeter.
3168, 12v output ok (AOG on or off OK)
Cytron output to 3163 or 3165 ok.
I take 12v from 5200.
Gnd connected to 1, 30, 39, 40
3160 to arduino A0
Was ok but not with 716. I take it directly near the motor.
But the wheels don’t move 
The only thing, that isnot connected is 5v pin29.
But i don’t need with aog 5.2.
No?
And 716.6 isnot connected.
You probably don’t need to connect 716.6.
But you need to supply the pressure sensor with 5 V on pin 29.
Have you tractor autosteer on? (pressed in where the steering wheel sign are! If not on then the security relays do not connect 3163 and 3165 all the way to the valve.)
Ok.
We need to activate something in AFS monitor?
Don’t know. Our T6 175 don’t have a afs monitor. We did not change anything in tractor computers.
Is your isolation Valve getting 12V, because otherwise the left and right valve doesn’t work.
I will check
I do have the monitor and there should not be a need for any changes in there.
Your problem must be elsewhere. Double check you get voltage to your valves when autosteer is engaged.
Also make sure you drive faster than minimum speed.
Or you must use the “drive” function in steer settings. Else AOG do not activate output to relay for isolation/dump valve.
A bit a different question, would you share the Stl Files from the 3d Printed Part, which holds the 40pin Connector in the Box?
I updated the first post to include STL and OBJ files for printed parts.
Hello dear sirs
I have checked with a multimeter directly on the solenoids.
12v is correctly receive by activation dump
Gnd is correctly receive by left and right.
But 12v is not receive by left and right, and correctly send.
I don’t know why.
Update.
I didn’t connect pin 6 remote engage… I have to connect it? If yes, where?
I didn’t connect pin 3 also…? I have to do?
Update
It is ok, it is working now!
The button in the right colon was disconnected!
