Adding a Trailer Brake Controller for 2016 GMC Sierra 1500

Question

Question:

I want to add a trailer brake control to my 2016 gmc 1500 truck it only has the flat 4 plug pin on the back. Can I add a 7 plug pin and still have the wiring going back for the brakes ? I have two other 1500s 2014 and 2015 and they came with the 7 wire plug at the back but the 2016 did not. All three trucks have the receiver hitch.

To add a trailer brake controller such as the Prodigy P3 # 90195 you will only need Plug-In Adapter # 3016. The vehicle should be wired for towing already and you can use the Adapter 4-Pole to 7-Pole # 37185 to add a 7-way plug if you do not have one.

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.…
