Swamp rat

Fixed. Embarrassing. I thought the fuse was good but it obviously was not.

This is a 2024 truck. I only continuity tested the fuse. Trailer is attached but the inside trailer lights that are not getting 12v. Have not tried to inspect the wiring harness. Does anyone’s 2024 work?

I don’t have +12VDC on pin 4 (AUX 12 V Charging) on my new 2024 HD. I didn’t realize until I recently purchased a new cargo trailer with inside lighting. All other turn and brake lights work fine. Trailer works fine on a buddies older truck. Am I missing something? I realize the truck is smart enough to not apply signals if no trailer is connected but everything works except I don’t seem to get power to run the inside lights. I found a fuse #84 for ‘TRLR BATT (30A)’ which seems fine. Ideas? I have apt at dealer in a couple weeks but any earlier help appreciated.

With so many changes to the 2024 HD, how about a dedicated thread just to the 2024. I’ve found that cameras are special. Trailer TPMS are special. No idea what upfitter AUX switches are compatible. What else? A dedicated forum would be nice.

Yes, I followed the steps exactly. Deleted the profiles and tried a couple different times but could never get it to switch profiles based on key FOB in use. Anybody get this to work with the 2024's?

The new infotainment system in my 2024 GMC 2500 HD allows me to setup separate user profiles for my wife and I. The user profile stores custom screen layout, radio presets, etc. as well as Google account properties for each user. There is a dropdown button near the upper left that can be used to manually switch which profile is active. Cool feature but I don't want to have to manually switch the profile. I want the user profile to switch based on which key FOB is being used. The user manual doesn't seem to reference this, but I've read in some forums that this should be supported but have never gotten this to work. Some forums said that the FOB needed to be in the vehicle when you created the profile initially. I've deleted and recreated our two profiles multiple times with no success. Has anyone gotten this to work with the 24's? I haven't been able to get my dealer to confirms if it is supposed to work.

Thanks for the reply posts. Installs look really nice. Makes me feel better that the fit is the same.

I have a 2024 Sierra HD on order and questioning fit for a truck bed cap. My truck will have a small fairing that will contain the bed camera and 3rd brake light. The fairing looks to extend mostly across the full length of the rear window and extends 3-4 inches back from the traditional roof line which then overhangs the rear window slightly. Has anyone installed a truck cap in this configuration? I'm curious how the truck cap fits around this fairing. Pictures would be excellent.
