I'm Not Sure About bout an 04 but most car manufactures use Vehicle specific harnesses. Unless your Jeep Had A Factory option that has been removed or a dealer add on that wasn't installed, the wires are for something. U can try a Repair manual or they may be optional for your Class of Rubicon.
instead of hooking to your jeeps power source try a battery pack first to see what engauges this way you wont melt any of your wiring harness on your jeep .they could've been old amp wires that they ran under the jeep?
we use 6/0 and bigger wires for acc such as light bar, tow packages and the like. if its unpluged the acc might have been removed at trade in. if you plug it in it might noy have a in line fuse and you could start a fire and or short your electrical system and thats expensive!!
