Denali2500Indy

Looking for where the pin would be for the DRLs, or is there a fuse somewhere I'm not seeing?

Having an issue with headlamp bulb connection. 1st off truck is 2015 Sierra 2500 Denali, using a volt meter and headlights on in manual I get 13.84volts, plug in headlight bulb. It flashes on for like 100th of a second then nothing. Check voltage again and it's at 6.82volts. What would cause this, is there a bad relay or something? Totally stuck and cant figure it out. Any help or suggestions are greatly appreciated.

New to this forum, purchased a 2015 Sierra Denali 2500. It does not have wireless charging, what all would I need to do to convert it over? If there is another post about this please point me in that direction. Thanks
