fixing the wiring in 2010 Nissan Frontier

[TravelBug80]

My coworker got a 2010 Nissan Frontier 4x4 with a tow package.

She &her husband just got a camper with an electric jack. The jack has its own 7 pin plug, but it won't work when they plug it into the truck.
Thing is, it worked fine on the other person's truck. They even used it to hook up to my truck a few days ago, so I could tow it home.

I can't help to checked the jack's plug, and the yellow/green wire is in slot 3, and the black wire is in slot 2.
I wanted to tell them to move wires around and maybe mess things up, but do you think the jack will work if the yellow/green wire switches to slot 4 and the black wire switches to slot 1?

Or maybe you guys got better ideas?

try to swap the yellow/green wire to slot 1 because the electric jack needs a 12v power source and the black wire to slot 4. If that doesn't work you should check the connector in the truck, it may be faulty.

Switching the yellow/green to slot 4 and black to 1 could work, but I'd suggest double-checking the truck's wiring first for any issues.
