HELP!

I will admit it I am not a Mechanic or an Electrical Genius. I have a Camper that has additional tail lights mounted to the bumper and after removing the old ones and replacing them with new ones I did something wrong because everything works except the Running Lights on the Camper. Brake Lights go on when I depress the pedal, Turn Signals work when I put them on But I don't have any running lights. Could someone please tell me what I did wrong? Everything worked before I took them all apart.

Remove any wires, go over them, any fuses, make sure they are not blown and are in the socket good, and make good contact. Also make sure the wire hookup is hooked in good...
