Available 5-Flat Wishbone-Type Trailer Connectors

Question:

Hi there. I have a tracker boat with a trailstar trailer, and Im having a hard time finding a new 5 flat wiring connector for it. The one that came with the boat has 10 wires 3 blue, 3 white, 2 brown, 1 green, 1 yellow, however every replacement adapter I can find only has 5 wires of the same color. Where can I find the proper replacement connector?

We do not carry (and I have not seen) a 5-flat type trailer connector with the many multiple wires for each pin that you describe. We DO have wishbone 5-flat connectors like # A40W5B which have two brown running light wires to simplify connection to the tail lights on both sides of a trailer. What you describe sounds like a custom-made part.

I can understand the three white (ground) wires especially if the trailer were made of aluminum which makes establishing multiple grounds more challenging since the aluminum frame does not conduct as well as a steel frame trailer. But the connector having three blue wires is more surprising. I suggest checking with TrailStar since this sounds like an OEM part.
