Alfa Milano(75) gold
First pass will be a PNP in to the L-junk plug.
I need to do this fast.
Will be using hall dizzy trigger.
Will feed a Street Fire CDI unit for spark
Using a old V3.2 with no step chip.
notes:
l-jet pin1 yellow to feed white of cdi
gray of cdi to tach white
red of cdi to coil power (green/black)
NOTE: Lo-Z Injectors
Ignition pull
with switch open (not WOT or idle)

Injection
Using old wires.
I need to look at the car but the diagram out of the online books page E-43
each injectors has a red wire for power via S2 relay looks UNFUSED!!!
