Recommended Custom Wiring Harness To Install Tailgate Light Bar On 2021 GMC Sierra

Question:

Hi, Do you make a wire harness for tailgate light bars? I installed C55384 harness but now my truck thinks there is a trailer hooked up. I dont want to cut my factory wires to hook up the light bar. Thanks

It sounds like you are looking for the Custom Wiring Harness for Putco Blade Tailgate Light Bars # P529005 which is a custom fit part confirmed to fit a 2019+ GMC Sierra/Chevrolet Silverado. This harness is designed to plug into the harness of your 2021 GMC Sierra which will keep your truck from recognizing the light bar as a trailer, and will not take up your vehicles existing trailer connector.

This kit is designed for Putco or Blade Tailgate Light Bars like the Putco Blade LED Tailgate Light Bar # P92009-60.
