Tips:

Better try CNF1/BOOT connection after read password (not resistor method as pinout above).
CNF is at the side of your MFC switch.
Boot is just a GND.

you only need Boot and green (ignition connected) and must change ecu canbus pins for boot different than password.
connect ignition directly to resistor.
