My understanding is that the CAN Bus terminals are only necessary for EVIC display.
I can confirm that if you give power to the (run/start pin) then it will work.
I just installed mine with connector A no connector b and it worked just fine. I later went to a junk yard and found a truck with one and took the pigtail. had the dealer activate the sales code along with my remote start. but yes it works with only the power wire attached Just splice into the pink wire with the light green stripe in the main dash harness that goes to the main 43 pin dash plug next to the brake pedal
