Could Trailer with Electric Over Hydraulic Brakes Have Trailer with Electric Brakes Connected

Question

Question:

I was curious if you set it up like he's suggest running a wire from the brake controller back to the second trailer how would you adjust the gain or second trailer be able to control the brakes back there and when these's a pulse train coming out of the controller to the electric over hydraulic system on the 5th wheel, how would that work with electric brakes on the second trailer?

So your electric over hydraulic brake actuator is receiving a standard brake controller output signal to tell it how to operate your EOH trailer brakes. So it would be possible that you could take this circuit (most likely blue wire) and extend it from where it connects to the actuator to the back of the first trailer so that you could then connect it to the electric brakes of your second trailer. You'd need 10 gauge wire like part # 10-1-1 (sold by foot) to get the circuit to the trailer wiring connector you have at the rear of your first trailer and connected to the 7-way you have there.

If you connected the second trailer like I described you'd only have one brake setting between the two trailers since it's one brake controller. If you needed to be able to have two different brake settings it would have to be done with two brake controllers.
