Hey guys, first time posting here. I bought a 2016 Chevy Duramax the other day. While looking at the truck I noticed an HDMI Cable and what appears to be a 12v power supply almost like a laptop charger coming from the fuse panel. Is this for a tuner? If so, what is the best way to figure out what tuner I can run with this setup? I know the truck is deleted but it is currently on a single tune instead of a DSP5 Switch like my last one. Any help would be much appreciated as I am wanting to reflash the truck to updated tunes. Thanks

Follow that hdmi looking cable back and see if there is an obd2 plug on the other end stuffed up somewhere. The other looks like a radar detector cord.

So it was actually just the other end of the hdmi cable stuffed up like it had been ran to something but was unplugged. As for the other wire, I think you were right on a radar detector because it was just tapped into a 10a fuse.
