Any guesses as to what this connector is for?

So I had the driver's side fuse panel off on my 2021 RST Duramx and I found what appears to be an inline fuse holder hanging below the panel.  I reached behind and found that it leads to a connector that was just hanging loose (unconnected) behind the plastic.  The other end of the wires seem to connect somewhere behind the light or 4WD controls.  

 

Just curious if anyone else has noticed this or knows what it could be???  Everything seems to be functioning on the truck as expected.

Definitely not factory whatever it is.

That would be my instinct as well...  But I bought it brand new off the dealer lot.

Let's eliminate some things, do you have the factory brake controller?

Yes, factory brake controller. Have the package with the lights in the mirrors.  4WD, but no Z71...

Still have your factory window sticker to see if there were any "dealer installed" items?

Yes, nothing listed.  However, the dealer I bought from does tend to try to sell you on a bunch of that kind of crap.  I told them off the bat that I wouldn't pay for any of it though.  I wonder if they had already prepped it for something, or installed something and then removed it (since the connector isn't connected to anything)...

Hmm, 7 cavity plug with 4 pins being used, does the "plug" in the bottom of the photo have anything on it? Any numbers, letters?

No, nothing written on it.  It looks completely "generic" to me.

Have you checked to see if it is "live" with a continuity tester? 

 

Once again, all just guesses on my part. The more activity we generate, will draw people to the post, and hopefully someone will recognize what it is.

Good call!  I'll check it in the morning.  Thanks for the help!

It's not too hard to remove the panel for the light/4x4 switches. Might give some insights.

As far as that goes, the dash pad above the instrument panel just lifts off with no screws.

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Injector update

      By CamGTP · Posted

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Winter Returned

      By Grumpy Bear · Posted

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
