2020 Ram 2500 4x4 - three connections behind the rear bumper I need help identifying.

These wires were tucked up under the bed which had to be removed to repair the bedside and install the aftermarket bumper. All connections are on the driver side rear cluster behind the rear bumper.

Connector #1 - four pins with four wires - red / yellow (white), purple / white, black and yellow

I’ve got a tradesman as well so I’m a bit stumped.

which would make sense of why there is nothing there. lots of plugs don't get used on a harness just depends on what equipment they have.

Which was my point...most of the time the wiring harnesses are all installed so that they can add whatever options are needed for whatever truck. If there are plugs under there that are used for an option you don't have, its still the same harness that is in other trucks...
