Is there an extra connection for a rear power outlet? I think so.

The extra hot wire in your trailer plug is for your camper if your towing one. This charges the camper battery while your driving and can discharge your truck battery if you leave it connected and are drawing on your camper electrical system. I found this out the while I was switching my trailer plug and found I had an extra hot wire. The fuse for this is either in the fuse box with the others or if it was added after production is in line at the left front fender corner.

When my running lights are working on my trailer my turn signal lights and brake lights don't work but if running lights are off turn signal and brake lights work?

I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.

You rewired your trailer and you have all of the lights but no brake lights?

Your trailer tailights are dual-filament, with one being the running lights and the other the brake lights. You need a separate power source from your towing vehicle's brake lights to power them. The easiest way to do this is go to U-Haul and but a set of their trailer towing taillight bulbs for your towing vehicle. The bulbs replace your standard tail/brake light bulbs, and they have two wires coming out of the base of the bulb. One of the wires connects to your trailer's running lights, and the other one connects to your trailer's brake light circuit. I'm trusting that when you re-wired your trailer, you ran two wires from the taillight socket, one for the running lights and one for the brake lights. In some trailers, the brake light circuit also doubles as your turn signals. Good Luck.

Trailer Lights Not Working ProperlyWithout being able to physically see and troubleshoot the defective trailer light wiring system [from the attachment to the vehicle wiring harness (s) all the way to each of the trailer lamps [light bulbs], one can only speculate.I suspect that the cause for part of the lamp filaments working properly while some don't is the result of connecting some wires to the wrong wires.
