Recommended Replacement Quick Connect Wiring Harness for a 2024 GMC Sierra 2500HD
Updated 12/22/2025 | Published 10/27/2024
Question:
I have a 2024 GMC Sierra 2500HD Denali with the factory tow package/towing computer and factory LED tail lights. Will this harness work with my truck? Will it interfere with the towing computer? Im reading online that you cannot tie into the towing connector on 2024+ model years. If this adapter doesnt work is there one available that will or how would you wire in any tail gate light bar?

Hey Brian, yes since the Replacement Quick Connect Wiring Harness for Putco Blade or Red Blade Tailgate Lights # P529004 is a universal part it will work great with your 2024 GMC Sierra 2500HD.
This harness is designed to be used to install your Putco Blade or Red Blade tailgate light so it should not affect your towing computer since the two circuits are not intermingling.
