I goofed up and now have to replace the cord that runs from my tow vehicle to the trailer for lights and such, how hard should it be?

I didn't replace the entire cord, but had to replace the trailer 7-blade plug on that cord. It was not hard to do.

I'd think replacing the entire cord, with the plug already installed, would be easier. You should carefully note where the old wires connect to the trailer and install the new ones the same way. I THINK the color codes should be the same on the new cord as on the old one.

I have the same problem. didnt secure the cord correctly and ended up with it draggging on the pavement. now have badly aabraded wires. how far back do you have to go to find where it connects to the trailer? didnt get a good look today as it is raining. thought I would piggy back on this thread rather than start a new one.

I guess I’m asking,where is the junction box located? In the batterey box or inside the trailer?

Thanks

Rick, I'd have to look in my trailer, but I don't recall any "Junction Box" at all. I believe my trailer cord attaches to a strip containing binding posts in the tongue of the trailer (in the battery box section).

And then the wires run from there to fuse box?

Or, to the battery, CB's in the tongue, brake circuits, or straight to the exterior lights. I don't think any of the TV wires are fused in the trailer, I think they all depend on fuses in the TV.

took me two weeks because trailer was parked 30 miles away- but i got it done! Jack was correct, as usual. just keep the correct wire colors in the correct place. Before getting started I puchased a ratcheted crimper, which may help in ensuring i made good wire to spade connections. Haven't tried on road yet to make sure trailer brakes are functioning correctly. but- knock on wood! I also took photos of all the wired connections before i started in case i had a few hanging around that were unaccounted for- which happened, and the photos certainly helped me track down there appropriate spots.

Our HiLo dealer sells five Hundred end pieces to the tow vehicle. It is easy to drag the cored or it gets corroded. We used to keep an extra end in our glove compartment. DH also keeps extra hitch pin parts as you are usualy far away from an auto parts store. Cheap insurance!!
