Trailer lights wiring

Hey guys, i need help with the trailer lights. I had to take out a lot of old stuff that wasnt working. The previous owner had already taken out the pump and the converter. We decided to redo the wiring completely because i didnt think i needed all of the interior loghts and would instead runn everything off of 12 v from outside. I got all of that done and it works real well, i havent added a air conditioner yet though lol so i dont know how good of an idea that was unless i hqve two different connections for that.

My question is these cords in the picture come in from the trailer harness , and when i reconnect them they arent showing any light in the back. I am thinking of running them and reconnecting them in the back where the sock thing in the bathroom goes in but i want to make sure i am reconnecting the right ones to the right ones, so far the wiring diagram i found doesnt seem to be correct- none of them are working. Unless i have a bad ground or something?

If I remember correctly, all of the wires are yellow and white...one color for power (12 v), the other is your ground. To determine which wire is for a particular light, you will need to "ring" them out...( disconnect one wire from the harness and connect a piece of wire long enough to reach the rear of the trailer and test each component with a multimeter set to "continuity "... when it gives a tone, you found it...label the wire and try the next one...can also be done in reverse...component to harness...2 people make it easier...hope this helps
