Hopkins Endurance 7-Way Trailer Wiring Installation - 2015 GMC Sierra 3500 Video

The Demco Hydraulic Brake Actuator part #DM72VR is a great option to replace an Atwood 82543. That said, it does not come with any sort of reverse lockout feature therefore in order to reverse without the brakes locking up you will either need to…

I went out to the warehouse and pulled Hopkins 7-Way #HM47210 from the warehouse to measure it for you. From side to side the mounting holes are 2-1/4 inches apart on center. And from top to bottom they are 1-1/2 inches apart on center. I have…

I do have an option for you but there aren't any direct wiring adapters to go from a 4-round to a 7-blade. Therefore, you'll need to remove the 4-round and install a 7-blade which is really your best option since this is far more common for…

The kit #23-26-27 that you referenced only comes with left and right hand 10" brake assemblies. The drums are sold separately. The typical hub and drum assembly that fits with these brakes is the etrailer 3,500 lb #AKHD-545-35-EZ-K. Even though…

While it is normal for trailer brakes to get hot from braking if yours are getting excessively hot and only on 3 of the 4 assemblies they are likely too tight and creating friction while driving. You can adjust the Brakes #23-26-27 that you have on…

Yes, what you described is very common and would work well. The part #HM47210 that you referenced can have it's 12 volt power circuit wire ran to a trailer battery that is powering an electric tongue jack. People do this all the time and it works…

The ground wire on a trailer's wiring harness (usually a white wire) should be firmly attached to clean bare metal on the trailer frame. The white ground wire on the vehicle's wiring harness should similarly be attached to clean bare metal on…

Here's what I'd recommend. If you have an exposed portion of the hitch crossbar to work with, use the #18136 no drill bracket. This fastens to the hitch crossbar using an included pipe clamp. You'll also use the #PK12711U 7-way mounting…

For your 1999 Ford F-350, an Integrated Brake Controller was not a factory option. The Factory brake controllers were not an option until 2005 models. For a great aftermarket brake controller, I recommend the Tekonsha Prodigy P3 #90195. This is a…
