Here are some pictures of my assembly on a CVX. Nothing special with all that is already done, except the modified PCBv2 which I share for those who are interested.
A wonderful line:
I use this little antenna from droteck on the front of the cabin:
For the motor I use this 12v motor (5.2–950RPM) which works really well 60Mm Geborsteld Planetaire Gear Dc Motor 12V 24V Cw/Ccw High Power Hoge Koppel 60PG60S As 12Mm Spiebaan Motor|DC Motor| - AliExpress
the PCB box is Bluetooth and completely integrated into the padding, nothing sticks out, no wires, just a few buttons for security. The PCB connected to the + contact starts and stops at the same time as the tractor.
for the WAS I use a linear sensor on this suspension bridge, hard to do otherwise.
On my github you can find the modified pcb as well as the details of the modifications. you will also have access to the list of equipment that I have used successfully!
