X2....was the same on my 2002 1500HD except all I had to do was install the 40 amp MAX FUSE in the designated slot in the fuse box under the hood. I do know that GM changed things up in later years (as stated in previous posts) but, it's all still in/around the fuse box area under the hood. On my old 2002, when I opened the fuse box cover, the fuse location/slot diagram was under the cover and was labeled "trailer 1" and "trailer 2" I believe.

I have a 2015 GMC Denali 2500 and I did not see any loose wire around my battery. I am getting this correct that I am NOT charging my TT battery when going down the road connected to the trailer? I need to investigate this further.

Check the "1 o'clock" position in you trailer plug to see if it's live (key off or key on). Sometimes they are already hooked up from the factory (trailer package) & sometimes it's left up to the dealer to hook up as part of there pre-delivery prep. but, they don't always remember to do this.

As part of dealer prep, the dealer is supposed to connect the power to the under hood fuse block. They did not do so on mine, and many others apparently.

Here is the tech bulletin on how to do it.

The wire is in a bundle taped underneath the battery.
You will need an M-6 nut and a 40 amp fuse (if it is not in the block already - mine was).

I also found out that if you push the tow haul button while the engine is running it will boost the current to the TT battery.


Your passing blinker also goes from 3 flashes to 6!

I installed a relay in the wire to my connector, and installed a switch in my dash so I can kill the power to the connector if and when I want to.

Check out this youtube video @1:56. https://youtu.be/x0x-2eKSmoM
This was the same for my 2011 Yukon Denali. You may have to hook up BOTH brake controller power wire & the trailer plug charge wire. Both were not hooked up on mine.
