Trailer Light Wiring Diagram for 7-Way on a 2019 Chevy Silverado 2500
Question:
Looking for a trailer light wiring diagram for 2019 Chevy Silverado 2500 HD to identify each wire
asked by: Jacob C
Expert Reply:
According to my research the following wires for the 7-Way on your 2019 Chevy Silverado 2500 should carry the following functions:
Green OR White/Green - Reverse
White - Ground
Blue - Brake Controller
Green OR Green/Purple - Right Turn/Stop
Red/Black OR Red/Green - 12V Power
Brown OR Gray/Brown - Running Lights
Yellow OR Yellow/Gray - Left Turn/Stop
The reverse light function green wire should be slightly larger than the green wire for the right turn/stop function (if you have the 2 green wires). You can also tell the difference between them by testing them using a circuit tester # PTW2991.
Your Silverado should have a US Car Connector plug at the rear which you can simply plug in a new connector like the Hopkins # HM40975 if your current connector got damaged and needs replacing. This will help you from having to do any splicing for a new connector. If you are looking to add one to the bed of your pickup for 5th wheel or gooseneck towing then I recommend installing a connector like the Bargman # 50-97-410 which simply tees into the existing US Car Connector.
Installation videos for both connectors have been linked for you to check out.
