Trailer light wiring question

Prayers sent....there used to be a standard for trailer wiring but no more. I recommend finding out everything there is to know about the current wiring and go from there.

strip it all and start fresh. It'll save you time in the end.

This, plus when it goes bad again in 6 months you'll know what you did to get it working in the first place. Trailer lighting is the bane of my existence.

Get a kit that has everything.

Take some time now and replace everything with LED's.

No more problems.

Park it on your driveway and buy/borrow a mechanics creeper to roll around under it.

Possibly drink some beer while working.

The guy at the launch looked at me with incredible empathy and disgust as he said “Trailer wiring problems huh” One of life’s great mysteries. We can fly a plane remotely on Mars but we can’t make a trailer lighting system that will last 3 years. It’s up there with missing socks out of dryer.

I had everything working but one side, checked the light box for bad bulbs etc it was fine and it’s gone downhill from there. I am going to follow the Ob advice, rewire the damn thing ( after helping me kill my arch nemesis ((4 to 5 year old mobile area swamp turkey) it has proven its worth.

I use the marine butt connectors from Hf and then shrink wrap, LED too. May have the clean the grounds every few years but have been on a good run so far.

Yellow is left turn
Green is right turn
Browns are park lights, running lights(this will run down the entire trailer to the each parking lights)
White is ground
Blue is brake, it hooks up to reverse wire on vehicle.
Make sure to ground the white wire to the trailer, drill hole, ring terminal, nut, bolt, lock washer.

Are you installing new led lights? What is the towing vehicle? Magnetic light kit may be a better option if you're rough on your trailer.

I bought an LED kit with wiring and the lights. Also I used liquid electrical tape, which is applied like rubber cement.

I did that too. Also soldered all connections and then covered the liquid electrical tape with shrink wrap.

Been good for about 5 years so far. At least until now because I probably just jinxed myself.

Both brown wires on your trailer, the solid brown one and the one with the white stripe, go to the single brown connector that plugs in to vehicle. I personally wrap the two trailer browns together and stick them in a heat shrink crimp with the connector brown on the other side. You can also just crimp one to the other, and use a splice connector on the unconnected tail light, but I have very mixed results with splice connectors. Also before I assemble everything i slide an extra piece of appropriately sized heat shrink on the wire before I crimp everything together, and I spray the wires and crimps with boeshield or corrosion X. Once you have everything crimped, take a lighter or heat gun to shrink the connector, let it cool for a minute or so, then slide the other piece of heat shrink tube over the connection, with an extra inch past each end of shrink crimp, and heat shrink that too. Loose or shitty ground seems to cause more problems with trailer lights than anything. Drill it into the trailer.
