Question:
I have an old gooseneck horsetrailer that we are rewiring and adding new brake assemblies to. On the video you have for installing brakes, the trailer you wired was only one axle, and on the brakes, you used duplex wire, running the ground back to the tounge of the trailer. My question is, with a 7-way RV plug, should I also run all my grounds 4 wheel brakes - 2 axles to the front or should I just ground each wheel near the frame like the manufacturer did 15 yrs ago? Also, is there any way you can tell me the maximum number of amps I can run for my clearance lights? Id like to add a fender light and 1 additional clearance light on the sides of my trailer, but dont know how many lights would be too many. Currently we have 2 mini-light bars, 4 running lights and then the tail lights on that circuit. Thanks!

You can ground the brakes right by the frame as long as the frame is a good electrical ground. The closer the ground is to the brake assembly the better.
I do not know what the maximum amperage is for the running light circuit on your truck. But it would take quite a bit to over load the circuit. There are a lot of LED lights now available for trailers that draw very few amps. For example, one of the Optronics LED lights we carry draws .048 amps where as an incandescent may draw 4 or 5 amps. It is part # MCL65AB and would use bracket part # A65PB. I have included a link to a page that includes all of our LED clearance and marker lights and you can filter the selection by shape or color.
