Adding a 12VDC cigarette lighter receptacle in the console

[Rappr]

I have a 2019 Ram 3500 Tradesman. I am wanting to add a 12VDC receptacle in the back seat in the center console where the vents are at. To do it, I need to find out if there is a 12VDC wire in there that I can tap into. I know that it has the USB “Charging Only” port but, I am not sure of the wire gauge for it.
Any one have experience doing that or knowledge of the wiring?

I put a dual USB fast charger in the back and wired it to the power wires under the seat.

Unfortunately, I need the cigarette lighter receptacle to power a Colman ice chest I have.

Unfortunately, the plug in my other posts looks nothing like the one you tied into. I guess I will need to break out my multimeter and do it the old fashioned way!
