just trying to figure out which color wire or pin number the ecu gets from the ignition switch so it knows to do its thing??

from the gregoprs VL diagram....
is it the violet wire that comes off the fuel pump relay? or the green off the fuel pump relay?

and when the engine starts cranking, does the ecu then switch the brown wire to the efi relay which gives 12v to afm, cas, etc?

and what exactly does the blue and white wire from the starter to the ecu do?

i dont have a working car to check all these for myself, so please feel free to help me.

thanks guys

well after more playing, i found that it was the anti-theft module that was the missing piece of the puzzle...
so all that is necessary is to hook all the rb30 pink wires together to the 'on' wire from the torana.

still dont know about that blue/white wire from starter to ecu??
is it to tell the ecu that the engine is cranking??

got a reply off calaisturbo, it tells ecu engine is starting. increases injector duty cycle.
sklines run it from ignition switch. holden from the starter.
