Okay so I was inspired by 2 threads here, one being the fog lights on with high beams, which I did and love. The other is a thread about putting a switch in the bed by the tailgate to turn on the car

Hello,   Good idea, but I took your step little different. I have the puddle light and I tapped into that.     This way, when vehicle is in "run" position, puddle lights and the cargo lights w

Just did this on my 2018 Sierra after reading the thread with a little piece of burner wire to test it out.  i confirmed these:

 

  1. When the light sensor is covered and you unlock the doors with the fob cargo and reverse lights come on (expected)
    • When you open the door after that you can see the cargo lights switch indicator light is also on (makes sense)
  2. With the truck off, and all the lights off (and the light sensor uncovered) when you turn on the cargo lights, the reverse lights come on as well. (expected)
  3. With the truck on, and in reverse, Cargo lights come on with Reverse lights (expected)
  4. With the truck on, and in park, (or neutral) hit the cargo lights switch and the reverse lights come on with the cargo lights. (expected)
    • ALSO back-up camera turns on. (makes sense, but unexpected)
    • ALSO you get the info center notice that the "cargo lights are enabled" (expected)
  5. Hit the switch again and the cargo and reverse lights turn off (expected)
    • Camera turns off (makes sense, and now expected)
    • info center notice that "cargo lights are disabled" (expected)
  6. Final unexpected condition (and I cannot confirm what's happening outside the truck as i am by myself at the moment)
    • In DRIVE, hit the cargo lights switch
    • get the info center notice "cargo lights enabled" but NO cargo light switch indicator light.
    • rear camera also does not turn on

I'm assuming that the lights on the outside will also not come on in this last condition as this is normal operation for this switch (at least in the 2018's) where you can enable the cargo lights and they are physically off in drive, and when you shift in to neutral or park they physically turn on as the switch sets the condition, but it is controlled/overridden by BCM depending on the gear shifter position.

 

This all makes sense to me and its a super easy quick mod to do, but i think i'll be doing it with the diode as i personally DO want the cargo lights on when i unlock at night and when i back-up, but I DON'T want the reverse lights on every time I put on the cargo lights.  It seems to me that the back-up camera will not be affected with the diode setup, although that is a nifty side effect i must say.

 

Thanks to everyone who figured this one out!

1.  I went into the settings on my '18 truck, and turned that particular feature OFF.  As I recall, it's in the "Convenience settings."  ALTHOUGH, my Puddle Lights fully work with the doors open, no MOD necessary, like was needed on my '15.

with/without it being covered, you can go into vehicle settings and disable those lights.

The puddle lights on the mirrors? Ya lost me here. ¯\_(ツ)_/¯ I’m talking about the cargo lights and the reverse lights. And I have no settings for any of the three.

i got a little lost with 24 pages of thread lol but does this trick allow the cargo light to be on while in drive? would be pretty cool to have for night offroading

It doesn’t. The computer still controls that part of it. This mod will allow the cargo lights on with reverse, OR the reverse lights on with the cargo lights depending on which way you put the diode in. And if you want BOTH, you just do it with a wire. Only side effect of that seems to be that your backup cam comes on when you hit the cargo light switch in any gear.

Having trouble finding this relay on my 17. Is it under the fuse box in the engine compartment?

Under the dash, by the parking brake.

Did this work? Were you satisfied with the result?

Hello:

I have a 2020 Chevrolet Silverado 1500 crew cab. I have tried over and over to get the diode to work and I just cannot get it. I connect one end of the diode into the blue wire and the other end into the  brown wire with the white stripe on it. On mines there is two brown wires in it. I just do not know what I am doing wrong, I have changed the diode around still nothing. I help someone can help me with this. For the brown wire with white stripe on it will this wire be for the cargo light.

 

Have anyone changed out the cargo lights and put led bulbs in the dealership said that it will not work cause of the current.

 

Thanks

It should look like mine, in my previous post (June12).  Pink has 27 (27 is empty), Brown has 26, put the striped end in Pink26 (Brown/white), and the other in Brown26 (Brown/blue).  If you have it that way, please post a closeup of your BCM, so we can further help you.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
