The electric brake that Camping World installed hooks up to the Highlander with a Hopkins brake plug-in. The cover to the Hopkins plug-in broke and I had Hopkins Mfg. send me a new one. They did not explain how the spring attaches to the cover, so I left it off.
I guess without the spring, the brake 7-pin plug-in came out during the trip and dragged on the ground. You can see in the picture. My question is this: Can I replace the cord on the trailer? And how does it attach to the box? And finally, how does the spring attach to the cover?
