In this episode, I'll explain how I chose a 7way trailer wiring system for my Spartan Manor camper and then show you how I installed it: lights, cables, junction boxes, lighting tests, soldering and heat shrink.

It was a pretty big project considering I only want to tow this trailer to my property and leave it there! But I wanted to set it up correctly while everything is accessible and in case my plans change.

Thanks for watching! And I hope this has helped you figure out if your own trailer needs a 4way or 7way wiring system.
