Question:
I have a 2024 GMC Yukon Denali and bought the lue Ox 4-Diode Universal Tail Light Wiring Kit for Towed Vehicles BX 8848. It did not come with any install instructions. I also could not find any videos for my vehicle. Do you have any instructions or videos that could help me with install?

Hey Susan,
We have not had the chance to install that specific wiring harness on that vehicle at our facility, so we do not have a video of it being installed unfortunately. I do have the instructions for the blue ox harness # BX8848 and I will attach it below for you to use.
What kind of coach are you going to be pulling that Denali with?
