Model 260BH Pin Box

[bbunce]

Our last camping trip of the year our trailer lights started acting up. Now they won't work at all. I have tried everything I can think of and what Google has suggested lol. I think the problem started in my pin box with some lose connections and because of that I am not 100% sure my connections are where they need to be. Of course every wiring diagram I have seen online looks different. The main wires I am not sure of are a red wire coming into the pin box from the battery and also a red/black wire coming from the battery area as well. I only have 1 black wire coming into pin box from the trailer disconnect box which from my understanding goes to the blue wires for the trailer brakes.

It's frustrating that it's this hard to find a wiring diagram for your model online.

Welcome to the forum

I assume your talking about the junction box at the tongue/kingpin. Depending on the year of your trailer, Keystone used standardized color coding for the trailer wiring. The umbilical cord is 7 wires and those should be standard. Are you looking for what color does what?

Welcome. A 7 pin tester isn't expensive and can come in handy tracking down wiring issues.
