Trailer re-wire

Howdy All,

Has anyone re-wired their trailer recently? If so, which supplier did you use? I assume there is a internet store out there.

Thanks

Jason,
I've done several trailers but never used the wiring kits. The kits aren't bad but wiring has always been problematic on trailers so I "upgraded". If you do get a kit, never use the "scotch lock" insulation displacing connections that typically come with them. They actually cut the insulation allowing moisture to enter the wire and corrode. The trailers I did were not box framed so I ran conduit to hold and protect the wiring leaving minimal wire exposure at connections. I upgraded to marine grade wire for the added corrosion protection. I also suggest using adhesive lined heat shrink crimp connectors or soldering and adhesive lined heat shrink tubing at connections. Then to eliminate grounding problems with using the trailer frame, I ran ground wires to all lights.

Jarret,
I used routing clamps:



I found aluminum versions of the one hole at my local electric supply.

Jarret,
I'd like to add that the conduit I use is the gray PVC belled end electrical

+1 for the redundant ground. Truth be told the redundant ground will probably fail same time as the bolted trailer ground but it makes trouble shooting 10x easier to have a reference point.

Another alternative to the pvc pipe is to use the smallest CPVC line (guessing 5/8 OD vs 7/8). That much smaller in this case will be more aesthetically pleasing.
