I just had to redo the wiring on the trailer and for some reason I am missing taillights, I have brake and both turn signals but no taillights. I ran new wires straight from the connector directly to the taillights and skipping all the side markers now just to get the basic necessities. Any ideas on what I did wrong?

Brown wire on a flat 4 plug is the tail/running lights. Green is right turn/stop. Yellow is left turn/stop. White is ground. Check your car/truck wiring also. Check for proper grounds. It's the most common failure. Are you using LEDS or regular bulbs? Proper polarity are vital in leds.

Just regular bulbs. There is a white ground wire bolted to the trailer up close to the hitch, same place as its always been since I bought the boat, and there are also a ground on each taillight on the back of the trailer again same place.

Check for power on the Brown wire at the lights. If no power check plug. If you have power check the bulb and lamp asy. You can remove the bulb and check the socket also.
