I just talked to them just now being I haven't gotten mine yet from the 13th and he said they were building them up and will get them out next week.  He did say they were fixing them to work with the new body styles.

Following this for sure. It’s -5 degrees out so I won’t be doing this until spring or whenever the hell we get some kind of winter thaw but I will also be doing this

Got the kit in the mail today, there are no further instructions included on what to do with the other connectors.  I sent them an email asking for some, I suspect you guys are correct tho - that it w

Good news, it works !   The new harness and the new installation instructions worked, with a slight modification.  Turns out the kit gets its power from the trailer battery circuit, the red/green wire

I got the modified harness back.   No documentation and the video on their web page doesn't really refer to the new trucks.  Anyway, they did add some notes the product page, explaining which of the 3 wires (black, red and red to trailer power) to connect.   I burned an hour today testing connections and such, no joy at all.  I wonder if they actually tested it on a 2020+ truck.

Doesn't appear to work with the truck running or off, ignition on or off.

Maybe the switch is just a bad one, not sure.  I took couple pics and emailed Gen5Diy, will let you know what they come up with.

Good news, it works !   The new harness and the new installation instructions worked, with a slight modification.  Turns out the kit gets its power from the trailer battery circuit, the red/green wire in the trailer connector.  The fuse for that is #63 (30amp) on the fuse panel under the hood.  Gen5 told me that sometimes this fuse might not even be installed, so I checked it and found it was blown.  In the new instructions there are two ways to connect the 3 wires (2 from the harness and 1 from the trailer tap) that connect to the switch.

Depending on how your truck was wired, you connect those 3 wires to the switch differently.  Pic 3 and Pic 4 show that in my truck the Black wire matches up on the truck wiring and the harness wiring.  But I had to use the instructions for the opposite setup to make it work. I think those directions on the Gen5 site might be mixed up, as I connected it as directed and blew the fuse.  Connected it using alternate instructions and it works just fine.  Not a big deal, clearly a new product.

 

Also you don't have to drill a hole in the bed for the switch.  There is a rubber plug on the side wall by the tailgate on both sides.  I think it's for one of those fold out handles or maybe a tool box accessory. Pic1.  I found that removing the clips on the supplied switch, allows you to insert it into that hole with no drilling at all. (pic 2)  I popped the tail light to make it easier to run the wires. Pic 5. Just pop the LED bed light out, (press up under the bottom edge with a plastic tool, there's a compression clip, pop whole fixture up and out.  Then you can fish the wire up into that hole, and up to the small hole that you can run those wires up the bigger hole..   You will need to extend the red power wire a few more inches to reach the trailer harness, but well worth doing so.  I also think that the switch mounted high like this will help it from getting crunched by cargo.   

 

All in all a great and easy to install feature. 30 minute install time.   Now I can open the tailgate and hit the switch to light things up without having to go back to the cab or even opening the door.  Remember that switch will have power all the time, so if you leave that switch on, you could potentially drain your battery.   This setup only controls the bed lights. but not the overhead light on the cab or the task lights which would have really nice, but I'm happy just being able to turn the bed lights on, as most of the time the cover is on anyways. The switch does feel a little cheap, but it seems like most of aftermarket automotive switches are that way, the rubber seal seems pretty good though.

 

All in all - well worth the effort, easy install.   The fact the switch fits into that ready to use hole is a huge plus.    Great support from the Gen5diy team.

Noticed the Gen5DIY switch kit was now in stock so I ordered one for my '18 Sierra about an hour ago. Already got the shipping notification that the part was shipped. That was fast! Looking forward to getting this one installed.

Does anyone know how to install the yellow wire tap they included?  I have never seen one like that....

The fat end is the one you’re going to use on the trailer wire. Just pull back the black plastic cable wrapper and tuck the end cap around the wire ( unscrew it and take it off) and then screw the long part in. Here’s a pic before I wrapped it up. 066d799e8a5bde9bda9bf91d489c76dc.jpg

I see the problem now,  mine does not have a fat end.  They sent me a butt connector style one.  So much for installing tonight, I can not find one of those any where around my house.  Are those style ones you can only get on the internet?   I havent looked yet but there is only one red wire in the trailer plug to connect it to right?

I’m pretty sure it’s this or a version of it.

I got mine the other day and got to it today. Wired it and tapped into the red wire and blew the damn fuse for the trailer battery. Not sure why but I’m assuming the wires on the plug were in the wrong spades. Oh well just going to get a few of those 30a fuses and try the other way and see what happens.

I’m 90% wired up but I need to extend the red wire so it can even come close to the trailer harness wires. Have to buy some tonight and see what other connection options are out there. Not sure how to tap into that red and green wire for power. There’s not much room to play with under there and I’m not entirely sure how the heck this connector is even supposed to work unless there’s a lot of wire to play with.

Did you have to remove or lower your spare tire to work under there? And is this connector for tapping into the power or for extending the red wire. I can see how it would be used for extending but not for tapping into the wire.

Nope you don't need to remove the spare.  Roll back the plastic cable tubing to expose the bundle on the backside of there trailer connection and unwrap it a few inches.  Then you can tug that cable apart from the others enough to attach the tap. Mine came with a different tap, a T.    a couple of posts back I showed the tap on the wire and what I think is the tap on amazon.  You could use that straight thru one to extend the power wire if you need to. I'd wrap it afterwards for sure.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      By Chuck FB · Posted

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
