Can Second Trailer Have Trailer Brakes Activated as Well

Question:

I have a 30foot Jayco Designers series fifth wheel with a frame mounted hitch. I would like To pull a trailer with electric brake behind the fifth wheel. Is there a break controller I can add to the fifth wheel that will activate the brakes on the second trailer.

Sounds like you are towing two trailers that both have trailer brakes. As long as the brake output circuit is completed from one trailer to the next the part # C57674 would work to send the amperage to each trailer. You will want to be sure that each trailer has 10 gauge wire for the brake output circuit like part # 10-1-1 (sold by the foot).

The blue wire of this adapter would need to get run to the output of a brake controller that is designed to handle the amount of brake assemblies your two trailers have.

Or, if you are planning on using the # C57674 on your first trailer for attaching to the wiring of the second trailer this would work as well. It would be just a matter of connecting each of the wires to the correct circuit to get it to work right.

It's going to be basically impossible to get both trailer's brakes to activate with the same intensity. One of the trailers brakes are going to lock up before the other most likely so you will have to compromise.

Typically we recommend that people do not tow two trailers. Also, it is not legal in all areas so you would need to contact your DOT.
