Hello. Would you like to combine the work record with the lift switch installed in the tractor? How could I best solve this? Sometimes there is also 12v on it!
if you have a PCB V2 board you need to connect the output to ground
so to reverse the signal you can use a additionnal relay
The 4 unused connector on that plug make me wonder if the switch is “double throw” and one set of contacts is not used or if that switch is single throw, but you could replace it with a double throw version. The switch should have a make and model number on it.
If that is the case then you could just use the second set of contacts for the work switch without altering the tractors wiring.
