The rectangular cutout for the switch block is 1.5" x 3.95'. The switches are "push and lock" then "push to release". When turned on, they sit a bit below flush and are back lit. When off, they sit more flush and unlit. They toggle relays in the added fuse box you can hear switching.

I just installed the Upfitter switches in my 2020 HC.Took almost 6 hours. It would have been 4 hours, until I dropped a screw under the center console. I ended up totally removing the console and Bose subwoofer box to get to the screw. It was found. Otherwise the install went fairly well. I'm sure I could probably do it again in under an hour if I had to. I was overly careful to not break/bend/stretch the plastic bits. I picked up the whole kit from someone who got one with their truck but decided to do something else. The kit I had was for a non push button start. Since mine was a push button start, I cut a square hole in my bolster and installed the switch block. I have the non-push button start black bolster (84487351) with upfitter switch cutout available if anybody wants it. $20+shipping. I'm near Seattle.

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...
