Perfect, very detailed, thanks a bunch!!The 4 pin and 5 pin won't have the 12v power.
I'd use the Curt harness, which plugs in between the Jeep factory harness and the back side of the trailer connector plug on the underside of the rear bumper.
This way you don't cut into any factory wires, if you wreck your truck, you unplug that harness and take it with you.
Mr_Bill probably knows the part number of the harness he used.
You crawl under the rear bumper, unplug the factory wiring from the back side of the trailer plugs in the bumper, plug the Curt harness into the factory wiring, plug the other end of the Curt harness into the plug where you removed the factory wiring.
Now you can connect into that Curt harness to get your 12v power and ground.
The fuse you'd use would depend in the size wiring you use to get to the truck bed, and the capability of the 12v outlet you use there.
Most 12v outlets have fuses ranging from 10 to 20 amps, depending on the outlet and so on.
Say you get an outlet capable of 15 amps, you'd want to run probably 14 gauge wire and use a fuse at the connection to the trailer harness no larger than 15 amps.
That way if you plug something in and it draws too much or a wire gets damaged, you'll pop that fuse back there because that 30 amp fuse for the trailer wiring likely would not blow before you'd burn the wiring to your 12v bed outlet.
For now I’d like to keep power to my Dometic back there, and immed future an ARB compressor.
