I removed some of my dash trim and popped out the square blank off plug to install a switch. I found two 2 wire plugs attached to the back of the blank off plate. Can anyone tell me if these are for the 120 volt receptacle that would have been there if my truck had it?

I can't open the file you've attached. Can you upload it as a pdf? Also I'm thinking that this mod may require a trip to the dealer to activate this circuit.

I purchased the oem plug for the dashboard and plugged in the connectors in from the back of the blank and nothing happened. I haven't messed with it sense then however I think it may require the power module and a flash from the big bow tie to get going. I'm actually coming around to activating it soon. If you haven't done that project yet let me know ill check back in and let you know how it goes

I did not pursue this for the 120 volt plug, but am curious to find out how it goes for you. Please post your results.

Wouldn't you need to have a power inverter for that to work? My truck didn't have this option either, so I just bought a cheap one for whenever I need to charge my laptop while away from the office/home, and it works fine for my needs.

I found out you do need a power inverter got one brand new off ebay $89 probably going to need a flash from chevy Ill let you know how it all works out..

Any update?
I already had the invertor module under the passenger side dash, and installed the factory receptacle in its place. still nothing. So I'm sure the BCM needs a check/update to get the power correctly going to it.

Let us know if you have yet to go down that route.

I haven't seen anyone mention replacing the switch bank above the power port. From the factory there is a button that turns on and off the 110v outlet. You would need that and a BCM flash to enable it. Good luck getting a dealer to do that. Hell, they want $150 to enable the GM fog light kit for my truck after I installed it MYSELF! It came with a code which I thought was part of the high price of the kit meaning that the BCM flash was included in the cost of the kit. NOPE! It's just an Authorization code to say, yes this is a GM kit and you're allowed to flash the BCM for the customer and charge them for it. They'll probably tell you it voids your warranty too since it wasn't a factory option or a GM accessories add on kit.

The two wires in the back of the dash will not supply 110V. I am really not sure what it is for but it wont work even if you just buy the plug. You would have to add a power inverter and wire it up to get power. You would have to find a 12V power source to power the inverter and turn off when your truck is off. There are some posts about this long ago. I haven't had time, but I do plan to figure it out soon.

 

You would pretty much have to wire the inverter, than wire to the OEM plug by splicing or building a harness for it work (What I plan to do).

Has anyone finished with installation of this, please? I'm planning to do same in my Custom 2020. I already purchased recommended power inverter (https://www.amazon.com/gp/product/B01KT26D68/ref=ewc_pr_img_1?smid=A3W15S426VVWJO&psc=1) and I also got OEM Power Receptacle for the dashboard (https://www.gmpartsoutlet.net/oem-parts/gm-jet-black-accessory-power-receptacle-84581301?origin=pla&gclid=EAIaIQobChMIu9-QmZm-_wIVUMOGCh1djwetEAQYASABEgKq7fD_BwE)

I'm planning to splice power from 12v socket to feed that tiny power inverter. This is the simplest workaround I've found all over internet to avoid BMC charges. Sadly, it will keep power running constantly for as long as the truck is ON, but it is what it is...

I would appreciate any help from members here. Thanks!

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      2027 GMC Sierra: Official Discussion

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
