So I've been chasing this around for a long time now. It's been going on for 6 years, but has recently gotten much worse. I'll be driving, and my gauges all drop and every warning chime goes off. Blinkers and lights still work on the outside, but nothing on the inside. The cluster back light is still on, but gauges not working. At first it would only happen in the extreme heat or cold, and only here and there(like every few months), which made me think there's Expansion and contraction, breaking a connection somewhere. Lately it has been happening almost every time I drive, and in any temperature. Most Recently even my head unit will shut off. If it is not reset by the time I get out of my truck the head unit will stay on and drain my battery. With all of the research, I see similar issues, but nothing the exact same. There seems to be a lot of ground issues With these trucks, and I've looked at everything I can find with no luck. My gut says it's a connection issue of some sort, whether ground or not. Any info greatly appreciated. I tried uploading a video of the issue, but it says the file it too large, even after cutting it down to a few seconds

Definitely a ground issue.
Have you run a diagnostic with a good reader?

What's a good reader? I've been able to go by AutoZone right when this is happening, but it doesn't throw any codes. I was wondering if there's a tool that can analyze the whole electrical system, but haven't heard of any. Something I found today, is there are several things that have been messed with on the wiring. The Serial Data Gateway Module has been removed before and one of the wires going into the harness for it have been spliced. A couple other harness in the same area have electrical tape on them, and there was a wire coming from the plug in the back of the cluster that had a piece of tape marking a wire. This truck looked new when I bought it with 10k miles, but had a lift and nice tires. I had wondered why someone would trade it in right away, but maybe there were electrical issues right when they bought it? I'll include a couple pictures of what I found today. All I can think right now, is to try and find diagrams for what each wire is, but I wish they weren't so hard to read. 

 

Edit: this site doesn't like me trying to add several pictures for some reason. IMG_8090.thumb.jpeg.b0eeba65aa56a0baf891f154bbe958a5.jpeg

I use an Autel Maxisys Elite but that is expensive.
I know not everyone will agree, but run it by the dealer and pay for a diagnostic.
It'll tell you a lot about what's going on.

At this point, I'm willing to pay to find out what's going on and fix it myself if it doesn't involve programming. With the SDGM thing, when I noticed it was messed with, I googled it to find out what it was. A bunch of stuff came up about recalls and info that makes me think it can be an issue, but I haven't been able to look into it much more. I spent half my day out there and gotta quite for the day, but definitely frustrating. I'll look up the tool you're talking about as well

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
