yeah it will change depending on the ecm used .....
according to a wiring diagram I have F12 is the pin for VS V6 Auto, that's for power/economy switching, the A9 is something different though for LPG.
MAP switching or power/economy switching is normally grounding the pin, that A9 for LPG is getting +12v applied to it .....

The 12 volts is so the engine runs on petrol, disconnecting the 12 volts from the PCM makes it run on LPG.

yeah I understand that, I'm just trying to point out its not the map switch we refer to in earlier ecms, its doing something different.
