Tail lights and running lights not working

I have power to my camper, and outside lights when hooked up to the truck. I have one rear light that will go on when I hit the blinkers or hazards. I have no running lights breaks or signal lights. I have test and have no continuity form the tail lights. I cleaned the ground wire on the camper and clean the replaced the portion of the 7 pin on my truck. Need some help.

Almost always when I come across a problem like your are having I find the ground is bad somewhere.

On my bumper pull trailers it turns out to be not grounded between the hitch and the ball. Often a drive around the block will fix it.

Check continuity between the frame of your trailer and the frame of your tow vehicle. Last time I had this problem I ran a ground wire between the frame of the trailer and the truck. My lights starting working so I hunted down fault.

I had that problem this Spring. Turns out it was poor connections of the trailer wiring harness to the truck wiring. Got those connections cleaned, new crimp connectors put on...and voila...lights!!

Also buy and use electrical contact grease, available from auto parts stores, on the pin connector.
