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:

> At first, I was building your Schematic for the Pressure Sensor, but in the Version 5, you just can connect Signal from the Pressure Sensor to A0 on the Pcb. Then just activate the Pressure Sensor in the Menu. Because I had the Problem, that when turning the Steering wheel, the count was only detected when steering in the opposite direction, stop turning the steering wheel or after a few seconds of turning. But with the built-in Option with the V5 it works great, when set to 1 Bar.

Edit:  
There’s an earlyer discussion about this on larsvest topic

Wire 5200 on 716-11 is my constant 12 V I can´t help you with the 3185/3187 problem as it does not seem to be same diagram as I have, (on mine 3185 stay at 0 volt because it does not have any pin at the back of column autosteer switch, and 3187 get 12/13 V when autosteer switch at column is on) I do NOT have the button at armrest, like you and fivefinnishfarmer have. It is A0 on PCB (arduino A0) for 3160 The other wires you also have correct. In the Ma…
