OK. Lets backup. This is really pretty simple. You have four wires in the 4 way connector. White, (which is the ground wire), Brown, (which is the running lights), and the green and yellow wires are for a combination of turn and stop lights. I can't remember which is which but it does not matter, you would find out very quickly when you turned on your turn signal.
If you have power at all three of the colored wires at the rear of your Jeep then your problem is definitely in the trailer wiring and not the jeep. You either have signal power of 12 volts or you do not. If you have to, just rewire the trailer. The brown wire goes to all the running lights, (tail lights, side lights whatever light you run when going down the road. The two other wires go directly to the tail light that they control. If you turn on your blinker, you should get the turn signal on the side that the blinker controls and with the brake you get both. To identify the right or left just test the yellow or green wire with your turn signal at your 4way to see which one it is.
Now, after having typed all that I will bet that your problem is a bad ground wire to the trailer. Make sure that the white wire is connected to a good metal ground and that your tail lights are grounded also.
These circuits are really simple. The hot wire lights up the filiment in the bulb, but it has to have a good ground to work. It should not matter if it is an LED light. They work the same. In some applications you might need a resistor, but in trailer lights it is designed to work with 12 volts.
Good Luck with the trailer.
