2016 Dodge Ram 2500 Diesel Wiring

I have found the post for 2014 Ram but would like to know if the wiring is the same. I need to install a vehicle tracker for a fleet vehicle and just need 12v constant, switched and ground locations the rest of wiring info would be helpful for later or someone else if someone has it. Thank you! BillFreedom Isn't Free, Never Forget 9/11

With regular key, or smart key?

Regular Key 12 Volts      Red (40A)      +      BCM under driver dash, black 4 pin plug (B), pin 3            Ground      (chassis ground)                      Starter      Lt. Blue/Tan (for starter kill only)      +      BCM under driver dash, black 24 pin plug (A), pin 19            Ignition      Violet/Brown      +      Ignition Node (ignition switch), black 6 pin plug, pin 4 Smart Key 12 Volts      red (40A)      +      BCM under driver dash, black 4 pin plug (B), pin 3            Ground      (chassis ground)                      Starter      lt. blue/tan (for starter kill only)      +      BCM under driver dash, black 24 pin plug (A), pin 19            Ignition      pink/white (for ignition sense only)      +      BCM under driver dash, black 48 pin plug (E), pin 27

Tip start key. Excuse my ignorance, but is the 12v switched tied to the computer and should it be isolated in any way? Just looking for a source that is 12 v when ignition on, should I use one of the feeds for the 12v outlet? Thank youFreedom Isn't Free, Never Forget 9/11
