Installing 7-Way Trailer Plug on Trailer with Electric Brakes

Question

Question:

Hello, I have a trailer that I need a new wiring harness for. It needs to be one that will run electric brakes. The vehicle that I pull the trailer with is a Chevy 3500. Do you have any recommendations for a wiring harness?

I recommend the Hopkins 7-way molded trailer wire connector # H20044. It will measure 6-feet long and provide you the functions required for your electric brakes. If you prefer a longer connector, the same item is available in an 8 foot length as part # H20036 or an 11 foot length as part # HM20048.

Please note that the color codes on these molded connectors are different from those usually found on a trailer. The wiring code is on each of the product pages.

If you don't have some already, I highly recommend using dielectric grease part # 11755 to help prevent corrosion from water exposure.

A junction box such as # 38656 would be worth getting because it will provide an easy way to connect the wires from your trailer connector to the wiring.

I've added a few videos and a helpful article for you too.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
