ISO11786 workswitch

Has anyone used the ISO11786 7-pole socket found in tractors as workswitch for AOG?


Edit: do i just connect the pin 4 to pin 9? V4 all-in-one PCB - #249 by Pat

Put a multimeter between the 2 pins and test for continuity with hitch raised and lowered??

No continuity, pin is either 12V or Gnd! You can wired it directly to an optocoupler input
