Trailer plug too short

What would be the best way to make my trailer plug longer? The cord just barely reaches the plug on my truck, and I'm afraid it will pull out on a really tight turn. Is there an extension cord somewhere I can buy or should I just buy a foot of wire and splice it in to make it longer? It is a standard 7 pin trailer plug.

Its easier just replacing the whole harness, the come in 4, 6, 8 foot lengths which you can find at Etrailer.com or on amazon. It connects to a junction box just under the front of the trailer.

Lots of them

Etrailer has them as well.

Long term I would get a longer harness and replace the existing one unless you are hooking up a 5er. They usually terminate in a junction box just inside or under the A frame. This would be cheaper and better and should only take 20min to replace wire for wire.

Best of luck.

I guess I didn't realize it was that easy. I like this idea. I'll go measure what I have and just get the next size up. I assumed it would have run all the way to the back of my trailer where my breaker panel is.

Most likely not. There should be a junction box underneath it hooks to.

Hopkins 7 pin outlet

We just installed a 7 pin outlet in the bed of the truck using the Hopkins kit. Very easy install, hardest part was drilling 2 1/8" hole.

It is in the hardware department, right next to the bucket of steam to operate your steam cleaner

If you replace make photos before disconnecting wires. Color code on new cord may, or may not match. Test the wires carefully.
