Interesting little purchase which ended up requiring another small project.
Bought a Setpower Fridge/Freezer to carry in the truck for trips and grocery shopping. I thought my fancy pickup had a DC power outlet in the bed along with the bed lighting, but no it didn't.
So I bought a wiring harness that was plug and play with the pickup, it's a 5th wheel harness that tee's into the bumper trailer harness and parallels it so the bed mounted trailer connector and the bumper one are both usable.
Then I've ordered a power outlet to 7 pin adapter.

Had to bore a 2" hole in the inside of the bed for the 7 pin connector and then route the harness up to it and plug it in. It was a long reach up in between the inner bed and fender area to plug in the connector.

It is supposed to be a light checker and 4 or 5 pin adapter as well as a power outlet.
