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

Just the spark box extra advance is added at the dizzy with the ported vac advance

Note vac advance is not manifold vac but a port near the butterfly

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!!!
