Small update on the :
Partly canbus on this tractor, but also PWM. Cables are identified, and soon to be connected.
Thanks @Raycorp, @andyinv and @BGunics for clues and help.
Could not find the WAS cables in the cabin. Measured 5v on the connector by the engine, but nothing at the connector behind the fuse-box on right trim.
Made a new signal cable from the connector by the engine and up to the AIO board. Safe and sound.
