Adding a Trailer Brake Controller for 2016 GMC Sierra 1500

Published 01/18/2018

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.
