They do light up too, the 4 blunt cuts out the bottom are for your connection. #5 is the roof beacon wire that is coiled near the 3rd brake light. (snowplow prep pkg)

I’m happy to report that my 2020 Black-on-Black GMC Sierra 2500HD SLE CC LB 4WD "L8T” Gas truck was delivery on 02/14/2020 with Upfitter Switches Factory installed.

Well the first picture is similar to the one in my truck. Just a different color. Well I added a 5 aux switch panel to it today. I didn’t want to cut into my dash just to add some switches. Plus I wan

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.

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.

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.

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...
