it is 5V so I need re-think this
I changed the coil mosfet resistors to 1K
at Q3 Q6 Q9 Q12 Q16 Q21
jumped gate drive to output.
added diodes out to ground this will clamp any negitive voltage on the outputs
5.1V zeners would be a beter but I did not have any.

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!!!

IAC
will use the same pins the powered the heater in the old thermo type
one pin goes to the S2 power fuel pump/O² Orange/black
need to add a flyback diode between the pins.
| L-jet Pin | Wire Color | Use | number in setup | ECIII pin |

S2 Relay enable
it looks like l-jet pin#28 Yellow/red need to go to ground to enable the S2 double relay
Fuel Pump/O² Power Control
l-jet pin#4 Grey/green looks to high while cranking and will power part of S2 fuel pump/O²
