Did you just buy the parts from the dealer, or is there someplace putting together a kit?mine is a '19, yes

Thank you. Just pull it out? I did try to both push and pull it as if it were a locking tab. I'll give it another try.
That’s pretty much the only parts availableHate to bump this older thread, but can someone post the part numbers for everything needed? I can find the panel, but nothing else
Great video and document. What if my truck didn't come with the Aux pdc?Last year, I was working on a video that explains how to utilize the AUX switches and AUX fuses. I had to stop editing the video to help a family member, so it isn't finished, but here is a preview of the video. Thanks to @Brutal_HO, @IronByron, and @Jimmy07 for the information that enabled this video.
Please let me know if anything in the video needs clarification.
Here is a PDF document that explains the AUX switches. The document is not 100% finished, so let me know if you have any feedback.

Great video and document. What if my truck didn't come with the Aux pdc?
Thanks. I did install the aux switches and got the alphaobd before I realized what a pain it is to put in the oem aux pdc. So, I ordered an aftermarket wired fuse and relay box and wonder if I can connect that to the enabled aux switches. I tinker a bit and did this with an aftermarket switchbank on my last truck, but that was easy. Is there a pinout sheet, that is easy to read for non electricians, anywhere in these forums?There's a couple threads here about adding the OEM switches and enabling it using AlfaOBD, but the AUX PDC & wiring would be aftermarket. Many are skipping the OEM switches and using the Switch Pro.
Thanks for posting this... super helpful. I was about 80% of the way there, and this clarified the last few questions that I had.
However, I just opened up my wiring kit for the first time, and now I have a new question. In all the photos and videos that I've seen, position two on the grey upfitter jumper plug is vacant... however mine has a blunt cut wire in that position. (Grey with a blue(?) Stripe).
Does anyone know what that wire i
What year and model truck is it?
You guys are fast.It's just listed as a "Dash PasstTru" along with 3 of the same (4 circuits total) coming from the "White upfitter jumper" (new for 2021).
Looks like they terminate at the firewall somewhere under the hood.
So those that asked for more pass-thru circuits, looks like you have plenty now.
You guys are fast.
Thanks, I just realized that I've been relying on the 2019 schematic because that's what's on most of the posts here. I just did a quick search and found the updated 2021 schematic, which shows that new wire (W550).

At first I was thinking that the engineers had resolved the complaint about only one AUX being able to route back into the cab, but looking at the under hood setup, nothing has changed, so I can't figure out what that W550 wire connects to.
Yeah, it looks like this all changed for 2021.Interesting. On my 2020 3500 HO that port #2 is blank. My wiring diagrams do not show a port #2, meaning no wire there.
I'm no help but interested in what you find out.
