Thanks for this post guys, going to ask the dealer to install these bad boys for me since we are waiting 3 weeks for my AMP XL power boards on back order.

The only thing I would verify is the knee bolster part number. I believe there are two in black. 1 for trucks with push to start, and 1 for trucks with a standard key. ----- I could be wrong, but the one that I got had the hole in it for push to start. I just cut the switches into my existing bolster so I didn't have a big hole in it where the button would be.

Yes, I still have the one with the push to start hole in it.

I have an idea, wondering if anyone has tried this.  I spotted this https://www.tailgatefix.com/ and they are just splicing into and interrupting the power to the switch for the center section of the tailgate to prevent it from dropping on your trailer hitch.  Why not wire it to an upfitter switch?  At present you would have to run wire to the back of the truck to make this work.  Unless that same wire could be found in the harness further forward in the truck.  This is the install video.  The important information starts at 5 minutes into the video.  

 

 

Thoughts?  Comments?

I have tried ordering these 4 different times, I have used the yellow sheet and the part numbers and they tell me they cannot find the part numbers and have no idea what an upfitter switch kit is. Are my GM parts guys idiots or am I doing something wrong? Help......[emoji53]

not too hard actually, just have to go through the different sections on gmpartsdirect.com 

 

heres most of the part diagrams for ya!  Think all im missing here is the fuse kit for the battery itself.. Remember different part numbers for the knee bolster/switches depending on colour! image.thumb.png.cc99229c94234e8299de8b03a1e308b7.pngimage.thumb.png.0108cfc79b348e4cb594421ac667d22a.png

After 244 days on order I have my truck. The switches are in the knee bolster but nothing is wired. The dealers not sure whos paying for it when I bring it back. A $64,000 truck and GM can't do it at the factory? Come on GM you can do better than that.?

For some reason GM doesn’t include the installation. It says in the installation bulletin it it is not paid for by GM, and dealers will not be reimbursed. Installing the switches is the hardest part. With the GM upfitter instructions, wiring only took me about an hour trying to figure it out for the first time. I could do it again in less than 30 minutes. It is nice all the mounting locations are there and all the parts are in the bag.

I can't even order mine, the parts idiots tell me the part numbers I give them from here don't exist [emoji2357]

My just picked up my 2020 2500HD Duramax. As I bought off the lot, and the truck I selected did not have the upfitter switches optioned, so I need to 100% self install.  I took a look under the hood, and the firewall pass thru doesn't seem to include the "nub" that is cut to allow the power pass thru. My truck was mfg in Feb 2020.  I can't tell from reading the past pages of posts, so I'll ask. Does the upfitter install work with diesel? I'm ready to order the parts, but as has been noted many times, the parts are not specified for the 2500s (although I get it that they fit), just not sure about the Duramax. Maybe the power pass thru is different?  I can select the Upfitter option on the chevy.com website to build a truck, so I think it will work. I'd just like confirmation.

 

Thanks

 

Edit:  I climbed up on a ladder to peer into the cavernous engine bay and the firewall. I looked way farther back and saw the "nub" that is used for the pass thru. I also went under the dash I spotted the connector taped to the harness near the fuse box. Sure sounds like it will work. Debating if I should just cut a hole in my existing (one button start version) knee bolster instead of buying the one with the outfitter switch cut out.  I guess time to order...

    • not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...
    • First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.  
    • I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
    • Is it an optical illusion in the pic or is the truck really squatting that much horribly?
    • My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
