Steering a 2022 MF7718S through the CANBUS

So, I've been experimenting with AgOpenGPS and the CANBUS. Turns out... it's pretty easy, if your tractor is steer ready. X183 is the socket I'm using here (under the panel behind your right heel), and that box has an Arduino Nano (3 for a tenner), an MCP2515 CANBUS receiver (2 for £9), a potentiometer and a switch. Notice that if you grab the steering wheel, the tractor's inbuilt safety systems disable the CANBUS steering, so you have to re-engage it manually to get it working again. Pretty slick! Got it going on AOG later that day, but no video - and ran out of battery/time before I could tune the steering properly. Looks like it might not be that bad tho!
