Couldn't but connect it. It is for a liner actuator on our baler. Every so often something glitches in the electronics and that one doesn't reset causing the net wrap to not shut off. I was making up a cable that would reach from there to the battery on the tractor so I could manually reverse it and cause a reset.
Remembered which outbuilding may have a couple left from a truck I worked on 25 years ago. Got lucky and found the one I needed.
