This is what comes out of my dash with the console removed
From the floorboard
And what my new center console has. I was able to plug in the usb outlets and cig outlet up front, but nothing out back. I need something to connect to the two large plugs into the console.

Most of that coming from the dash won’t be used with the exception of the two orange covered wires. That connects in with my harness and carries the 120v circuits to the rear of the console. For the rest of it, you could trace back to the X61A junction block next to the brake pedal and remove.
Here’s what one version of my conversion harness looks like. It connects between the floor connector and the large 42 pin console connector, smaller gray connector and the two 120v connectors.
GM used two different types of floor connectors that would supply a jump seat on suvs without center consoles. Either a 16 pin or 23 pin. I’ve primarily seen the 23 pin on 2015 models.
16 pin
23 pin
The floor connector is located under a flap in the floor liner under the passenger seat.
For the harness coming out of the floor in yours, it looks like a modified jump seat harness. See if you can follow it under the floor liner to see what connector type you have.
