Trailer wiring

[Torvy]

So the dogs discovered that our trailer's wiring plug was a great toy. They tore the entire front third of the wiring out.

Oddly enough I had moved the trailer up to a work space close to the barn so I could fix a minor problem.

It's a 14'x77" utility with HD Axle and brake.

Need some opinions. Should I try DIY, or take it to town?

If I do it myself, is there a full harness for that type of thing or do I need to just get individual wiring and string it myself?

Any tricks, suggestions for storing or hiding the connection so the beasts leave it alone?

Thanks

If you are capable, DIY is pretty simple. You can start with a connector/cable and junction box for the front end.

If 6 wire, you can buy this:

Or 7 wire:

With butt connectors you can make it like new.

As far as protection, slide a piece of PVC pipe over the trailer wire

I have something like this on my horse trailer to protect the plug when not in use. Etrailer has plugs with 10' of wire molded into the plug. Most trailer dealers that have parts should also have it. You can then splice it to your existing wiring. Cover the butt connectors with heat shrink to help protect them from the weather.

My trailer wire routes over the top of the frame by the jack. When I replaced the battery box and did some wiring repair, I mounted the box on the jack with U-bolts.
The replacement wire with the junction box would be my choice. I added a junction box to my existing wire and it made it easy to make the connections while keeping them organized.

When not in use, I wrap the wire around the jack and place a five gallon bucket over it keeping everything out of the weather and somewhat limiting curious dogs.

All of my trailer wiring connections are soldered and shrink wrapped, butt connectors for emergency repairs on the road only. Same on the vehicle side and dielectric grease is your friend with plugs and receptacles. When I go to use my trailer after sitting for a year or two, everything still works like it's supposed to.

When I was doing my rewiring, I took the time to remove, sand and paint my jack. To limit the effect of weather, I use this bucket. The breakaway switch is somewhat exposed but I do have the wires to that encased in plastic tubing and secured to the frame.

I'll do crimp connectors if they are the heat shrink type & I can manage to crimp them without damaging the plastic. I prefer uninsulated crimps & heat shrink though. Crimps are as good or better than soldering if done properly. Unsealed is never right for external wiring, except for emergencies.
