You posted in the 4th gen section so lets start with what year your truck is so we can better help you. The video you saw was likely them installing the SGW bypass which may not be needed
 
Let's start with a few questions.

Phone/tablet/laptop?

You'll need:
  • An app
  • A supported OBD Reader or cable
  • A security gateway Module (SGM) bypass cable
The SGM bypass cable we use for HD plugs into the CAN bus blocks behind the headlight switch bezel. No need to remove the instrument cluster. That youtuber is ignorant of the best option.

  2. A Bluetooth interface such as OBDLink MX+ or OBDLink LX (cheaper than the MX+ if you don't need iOS support or use on Ford or GM (MX+ comes with a choice))
    • or vgate vLinker MC or MC+ works as well as the OBDLink and is half the cost.
  3. And a bypass harness to bypass the security gateway module so changes can be made:

Thread 'AlfaOBD'

Has anyone played with AlfaOBD on their 2019 HD's yet? I'm curious if anything is accessible to "change" and if it just works. There is lots of different info out there on other forums, but i haven't found anything in regards to the 2019's.

EDIT: AlfaOBD does work, here is the what is needed to use it on 2019 and newer HD Rams:
- The Android app from google play store, or windows download from AlfaOBD.com. (Windows version strongly recommended) (AlfaOBD is Windows/Android only)
- A Bluetooth interface such as OBDLink MX+ or OBDLink LX (cheaper than the MX+ if you don't need iOS support...
