Work Switch ISO 11786

Hardware Section Control
1

Hello,
I want to make automatic mapping of field when the hydraulics are raised or lowered.
I already found out that the work switch pin is intended for this, but I wonder what I should connect to it, GND or can I also connect voltage?
I had the idea of ​​getting the hydraulic position (raised, lowered) from pin 4 on the ISO 11786 7 pin connector that I have on the tractor. If anyone has done something similar, please help, because I would not like to complicate things that may not be necessary at all.
I have PCB version 4.x.

Thanks for answers.

You can wire directly.
The workswitch pin from the board can receive from 0 to VCC (to 40v actually)

It will switch from low to hi at around 2-3v, draw nothing above 5v and around 15ma at 0v I think.
