Boat trailer Problem

    2010 TRD Tacoma. Came with the trailer hitch etc.

    Rewired the boat trailer today with LEDs. Lights work but the left side is dimmer than the right when putting the left signal. When headlights on its like the left side turn signal does not work at all. Also, when headlights are on it seems the brake lights don't work on left side. When Headlights are off, all is good except for the dim left turn signal. I double checked all ground wires on left side and even have the ground wire on the trailer bolted directly to trailer frame. All contact spots for ground were cleaned B4 application. This is only on left side. I had the same problem with my 04' 4Runner. But when my trailer lights stopped working all together I decided to put new LEDs and new wiring.

    The only common link between the 10' Tacoma and 04' 4runner is the 7pin to 4pin adapter.

    Anyone else has/had the same problem?

    Any advice??


    Thanks in advance

    Check the 7 pin on the truck for corrosion, mine had got water in it over time and I had to replace it.

    Thats the only thing I can come up with. I was just curious if anyone ever had a problem with the 7 to 4pin adapter. It would be hard to believe that something could be wrong with the 4Runner and the Taco. Also, the trailer is only running 2 lights, so I'd doubt that overload would be an issue.

    it sounds like you answered your own question.

    the adapter my be faulty internally

    the quickest way to solve, get a new adapter and verify if the problem.
