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

Just restored my 89 SN trailer. Bought all the parts (including wiring and lights) from Amazon except for the trailer coupler which I bought from etrailer.com.

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 http://www.bestboatwire.com/marine-wire" rel="nofollow - marine grade wire for the added corrosion protection. I also suggest using http://www.bestboatwire.com/marine-electrical-supply/wire-connectors/heat-shrink-terminals" rel="nofollow - 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.

How did you attach the conduit to the trailer? Screw into the inside of the channel and a clamp?

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

Thank you, sir.
Restoring my trailer this summer while my boat is in a slip.
Now I just need to source some tread plate locally.

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

Thanks, Pete. I'll put this all in my notes.
Leftseat88, I got an LED kit from etrailer. I'm out of town right now so I can't speak for it's quality, but the price wasn't bad. I'll check it out when I get home in a few weeks.

+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.
