Mike's correct in that the cargo area stays lit only as long as the lights normally stay on when you hit your unlock on the fob. I dig that though - nice easy way to check your load with just your fob at night. Since I added two diodes, one going each way, the other added benefit is that now when you turn on your cargo lights with the switch on the console, the reverse lights will come on, which gives you added visibility when loading stuff behind the truck at night. In that scenario, the reverse lights stay on for 20 minutes, which is the set timer for the cargo light switch. It also turns the cargo lights on when you are put the truck in reverse. If you have the backup camera it adds a little extra visibility at nighttime. I like it so far. My only concern is the dealership noticing it and busting my chops about my warranty. It's pretty obvious when you unlock the truck and the cargo light come on. I just can't see how they could blame this mod on any substantial issues. If I take it in for anything electrical related, I will pull the diodes out first.

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

So when I look at this mod, it's convenient to light up the area prior to leaving, and also backing up but that's about it..

I find it convenient anytime that I need some extra light on the back end of the truck such as exiting, if I drop something at night, loading the bed, trying to find something in my tool box, in reverse, and other times. Just need to have the cargo lights on with reverse diode mod performed and your golden

As for dealership issues, they shouldn't give you any. Plus they can only bust your chops about warranty issues if they can physically prove that the diode has caused the issue that you are experiencing. They can't legally just say "well we think it was caused by this" and void your warranty. Magnuson Moss Warranty Act states that they have to be able to recreate the issue and the cause must be from the aftermarket equipment that is in question. One of my dealers thought that cargo lights on when unlocking at night was impossible, they learned with my truck it is possible and they are considering doing this mod to some of their trucks on the lot, or offering it as a "dealer installed accessory" when you purchase your truck from them lol

Thanks Mike - that makes me feel better about it! That would be pretty funny if they offer that - I wonder what they would charge.

For those of you that used a wire for this mod - what gauge solid wire did you use?

 

I'm assuming you used solid wire to be able to push it in?

 

Or did you just solder tin up some stranded wire?

Hmmm...this interests me...I just did DPN old to DPN new (GM mirror kit, door harnesses and jumper harness) and GM does not support a calibration change for the mirror swap, only DL8 to new DPN and DL3 to new DPN for their camper mirror kits. Unless they change their minds about this, I may try this diode deal to get the mirror cargo lamps to run in reverse (my HD is pre AVF).

 

Those that have done this mod in general, can you still run the cargo lamps normally in park and neutral? The diode mod just enables them in reverse (if you choose to run one diode instead of two or a lead of wire)?

I just ran into a situation with my 2015 when I was hauling a load in the box and I wanted to check it while driving with the cargo light............ thats a big no! So i thought if I hit the key fob lock/unlock it would come on.........thats a big no also. Anybody found away to be able to turn the cargo light on while driving? I realy dont want to add another light and switch if I dont need to. I just ordered the under rail kit to instal so maybe I will just switch that from the front.

You can switch into neutral to turn on the lights. Will turn back off when youbswitch into drive

Thanks Mike1220, I guess that will have to do. Better than nothing. Its always nice to use that light to get the attention of tailgaters and people that have their brights on all the time!

Hey guys, didn't quite find what I was looking for. I have a customer with a 2015 and the LED back up lights in the mirrors.

 

Anyone know of a way to turn them on while the truck is in drive?

only way will be to use an aftermarket switch. Buddy of mine, whom is also a member on the forum, did it on his 1500.

 

you'll need to use a momentary (or latching switch, whichever you prefer) and attach it to a power feed, use a diode to prevent back-feeding from the switch to power, then run the switch and again, diode to the cargo light circuit at the BCM, preventing any back-feeding from the BCM to switch. This should ensure that nothing can be back-fed and fried.

      Some Assembly is Required

      By Grumpy Bear · Posted

      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.

      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.

      when it's greyed out that is it's way of telling you that it's downloading the patch in the background. Eventually it will be fully downloaded and then it will prompt you at ignition shut down to run the update. I highly recommend doing the update once you get home and can run it a few times. I've had several issues with updates not going the first time around and I had to retry the update multiple times in my driveway before it was successful.   Some updates are huge and take awhile to download. You can help it by connecting to your home WiFi and keep the truck on service mode for the ignition and keep it alive for awhile on a battery charger too. There are specs it needs to be in for updating such as a full enough battery charge, no running ignition, etc.
