Strange Trailer Light Issue

Ok, I am gonna try and explain this so it makes sense. Replaced my tail lights with LED about a year ago. I was having some issues the last time out with brake lights not working so I changed the 5flat out on the trailer. Here is what is going on now. With just running lights on---Port side all lights onStarboard side only front Orange marker lightsWith Brakes appliedPort Side rear light only the outside LEDs are on (all marker lights still working)Starboard side the all the LEDs are on (still only front orange marker light working)Port turn signal nothing happensStarboard side turn signal works fine. I have all the colors lined up as far as I know, it connected to a 2014 Jeep Grand Cherokee. This has me stumped, If no turn signals worked or no brake lights or no marker lights it would be much easier to trouble shoot.

When in doubt check all lights are grounded, then check your grounds again. My tractor haulin trailer lights used to do random things until I : 1) sand my ball off a little or 2) I hook up and drive about 3 miles and everything starts working. I ran an extra ground to the frame of the trailer and a ground from my truck frame with butt connectors. Now they work great.

Solved my light issue by installing a jumper ground wire around the trailer hingejwt

Does your trailer have the breakaway tongue? Some people have had to install a ground wire that jumps from the trailer frame to the tongue.

Well I got down and started going though all the connections on the trailer and found a bunch that had pulled out or fell out or something. I am kind surprised how cheap a connector they use. these are going to get wet and they are not shrink wrapped or anything. I really want to rewire the entire trailer now after finding all this.
