Is there a menu option to enable/disable the jack?
The reason I ask is yesterday we could not get ANYTHING out of it. Got the DVM out and all pins were dead with the 4-way flashers and lights on. One pin ought to be always +12V and another GND but to no avail. Until today of course.
Went and bought a cable with LED's in the plug, tried out the factory plug in the bumper 1st and it worked, went on and tested the one in the bed and it worked, plugged in the camper and it worked.
I can't for the life of me tell/understand the difference between yesterday and today other than 24hrs transpiring and I spent more money. I did notice the dash says "trailer detected" and "trailer disconnected" in the message displays.
Which made me think that it might be some sort of menu option or something on a relay?
