Well during our move to AZ a trailer tire blowout took out all but one rear light on our cargo trailer. Did some inspection on the trailer and I want to rewire the trailer. Not happy with factory wiring. Has anyone else completely rewired a cargo trailer? I am thinking of running the wiring inside the walls all the way to the back. The main frame is a tube and will not be easy if possible to fish a wire all the way down. The wire that got pulled ripped apart is inside the frame somewhere so I cant attach the new wire to it and pull it through. Will there be any pitfalls to running the wiring inside? I am going to run the electric brake wire in the frame as those are still intact and can pull the new wire using the old wire. I also want to add interior lights. Any recommendations on where a good source for those? TIA

 

i used 1/2 pvc pipe

 

You really don'[t want to run wiring through the frame tube. Water will get in there, and the wires will sit in the water until it dries. Or freezes. If it's inside the frame, you won't be able to see it. If there's a problem, you'll have to pull it all out for inspection.

Run it through some good abrasion proof currogated tubing - standard automotive stiuff. Use adel clamps to attach it to the frame rail. Be sure to use quality primary wire that can hold up to exterior use. The cheap stuff from Pep Boys won't cut it.

Check with WaytekWire.com for everything you need. Even interior lights.

 

Thanks, so running it inside behind the walls should be no problem right?

 

My cargo trailer is wired on the inside. There are junction boxes for access to all wiring, each light or set of lights is wired directly back to the junction box. It makes fixing problems very easy and would allow you to get home if there is a short just by disconnecting problem lights. www.waytekwire.com has a wide variety of wire, lights, looms and connectors if you want to make a high quality installation. Waytek has great prices and excellent products. I have used their stuff on several utility trailers and had great results.

 

what kind of junction boxes? Like the typical 120V boxes? I like that idea. How is the wire passed through the sides? Did you have to drill holes through each upright?
