I have a 2015 2500HD. Recently replaced the under hood fuse box. My new one doesn’t have terminals for both the MSB DRVR or MSB PASS. Both 40a. Any idea what these are for?

The truck did come factory with fog lights. I’ve read the relay is unserviceable.

No one? I’ve Taken the fuse out for now.

I have a 2015 2500HD, 6.0l. Its been a great truck, only a few issues. I have 35w morimoto HIDs in the low beams, morimoto LEDs in the highs, and morimoto LED fogs. ive been having some issues with intermittent firing on the low beams, but that’s not what this is about. I got in my truck this afternoon and I noticed my fog lights are on. All I did was unlock. They are dim, and sometimes one flickers. They brighten up when I push the fog on, but they never fuller go out. Any leads fellas?

James did you ever find out what the issue was? I'm having a similar problem. I just replaced the battery and my radio and speakers cut in and out for a couple minutes after starting the truck, then it clears up. Tried BCM reset with no luck
