I was going to install a Brake controller today using the factory plug under the dash. Anyway on the plug it says 15 amp max on my other trucks I always used a 30 amp breaker to the controller, for trailers with 4 brakes(2 axles), is the factory harness only good for 2 brakes(1 axle)? If so is anybody using it for trailers with 4 or more brakes without problems? Or are you not using the factory plug at all?

Hi Jed...Third factory harness, on 3 trucks, with 2 different controllers, and 2 different dual axle trailers, and never had a problem.

 

No problems with the factory harness with two different dual axel 4 brake trailers. But I used a larger ground wire than the factory harness (the instructions with my controler said to use the same size ground as power so I did).

 

Thanks guys no worries then.

Two axles (four magnets) will draw no more than 12 amps anyway. You are fine. However, Dodge should use heavier gauge wiring for their electric brake circuits in my opinion.

I pull a 2 axle trailer every day and have no problems stopping with it. All 4 tires have STRONG braking abilities.
