    Looking at your pictures and descriptions I can’t quite tell, did you keep the wiring for the running/brake lights entirely separate from the 12V system running off the battery in the tongue box? Specifically, are the running/brake lights powered by your tow vehicle via a wiring harness?

      Yes they are completely separate. The running lights plug into a wiring harness on the tow vehicle, and the connector trailer side originates from the tongue box.

    The last three images of this page load image 6227. I was given a trailer this week and found your page. My electrical experience is low. I’d like to know what the controller with the LED screen is in the last picture. Make and model, then I can Google it’s purpose/integration. It looks like a power reading instrument … ? Thanks for the amazing information on the page.

    Great trailer! Can I ask where you got your fuse panel from?

    • Thank you!

      The Fuse block is a Blue Sea Systems 5026 Fuse Block w/cover. I ordered it on Ebay for $45.

        Thanks! The Blue Sea stuff looks pretty good, I think I’ll be using them in the future. Cheers!

    Ryan, I may have missed it in your write up, but how did you drill those wire runs into the walls? Did you already have the inside skins on when you drilled them? I ask because I am considering the clearance issues of a typical drill and how to go about making those holes in such a tight spot. Example…the tail light run at the bottom that runs between three foam panel cutouts.

    • Good question! I did my dry fit of the wall panel before applying the inner skins and marked where all the lights and wires should go. At this point you can take down the walls and get a drill in there to drill all your wiring runs. When you are doing this step take the time to account for the number of wires and their width and test that they all fit as expanding the holes once the inside skins are on is very difficult.
