I'm moving all my KC offroad lights from my 2012 Silverado 1500 to my new 2022 Silverado 2500HD (driving lights, foglights, etc.).  I have a Ranch Hand grill guard on the 2500.  I installed all the light mounts on the grill guard and am ready to run the wiring up to the drivers side of the engine bay to my switch panel.  Then....I did a visual inspection and was bummed.  First issue to deal with is keeping the wiring away from the grill shutters.  Second issue...I can't see any path to get the wiring into the engine bay either at the bottom or top of the grill.  Chevy seems so concerned about air flow that there aren't any gaps I could see for routing wiring.  Doesn't help that I have the Z71 package so more closed areas underneath.  Looking for some expert help.  Also, I'm guessing those two grommets on the left and right firewall are the only way to get wiring into the cab?  Doesn't look like can can get much wiring or connectors to slide in those rubber nipples on the grommets.  Seems each Silverado generation gets harder and harder to modify.  Thanks.

I wish my ordered truck would show up and I'd look under it to see.  Can you run the frame rail and pop up through a grommet on the floor?

I only have my 6 gang switch panel power and control box wire going thru that main wire harness. Close to the steering column.  A bear to get thru there i had to very slowly make a hole using a small drill bit and a larger Flathead. The fire wall grommet is separate from the under the dash grommet. It's possible just a lot of  bending . To get yourself down in there and under the dash.

 

There is also a rubber grommet just under the driver side carpet. That my amp step power wires run thru you could possibly enter thru there. And run across to the seal plate cable tray and up and under the dash. Certainly easier than the firewall grommet.

 

As far as the wires up front yea its tight a lot tighter than the 14 to 18 trucks. Almost have to go down by the driver side headlight and come back up from the bottom to the bumper. practically skipping the entire shutter and radiator area.

I even noticed there is a separate bottom baby shutter system. Where the transmission cooler or oil cooler sit in between the tow hooks and fog lights.

Have you tried Upfitters switches?  see the below thread.

I don't think upfitter switches would address the issue of routing wires through the grill area as they are installed in the dash. I ran my horn wires through the driver side by the headlights and came back around as mentioned by Leem.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      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.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      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
