For simplicity sake I went with batch firing injectors and waste spark ignition system, so the compact\slightly cheaper Microsquirt would work fine for me. I will only need one crank sensor and a 36-1 wheel welded to my crank.
My Microssquirt input/outputs are the following.
Inputs are:
crank/hall sensor, shielded from the shielding of a coax cable. Thank you A. J. for the tip. (no need for cam sensor)
coolant temperature sensor (Chrysler sensor)
air temperature sensor (open element Chrysler sensor)
throttle position sensor (Stock Chrysler sensor)
ethanol sensor (GM sensor)
o2 sensor (AEM Uego with 5v output)
manifold absolute pressure sensor (GM 3 bar map)
knock sensor (knocksense controller www.viatrack.ca)
A/C sense wire
Outputs are:
idle control (on/off solenoid, not the stock stepper motor)
tachometer
two set of Ignition coil (goes to 420a coil)
two set of injectors (75lbs low impedance injectors with a Volvo injector resistor)
a/c cut off relay wire
fan relay wire
fuel pump relay wire
Boost control is handle by my HDi electronic boost controller, and I am very happy with that.
Added an external voltage regulator from a 80's dodge truck, super easy to do.
Megasquirt has more options I'm sure, but I don't need them, why pay for them?

Separating engine harness with body harness.
Test Mounted.
All needed wires labeled.
Made bracket for crank sensor, using metal from the shifter bracket on top of the transmission. Will have to reinforce the bracket after the crank is welded to 36-1 wheel.
[/QUOTE]Marked where the 36-1 wheel needed to be welded to the crank pulley.
Welded and ready to be worked on.
Painted the crank and bracket.
Some people have coil on plug, I have coil on distributor!
Mounted my 420a coil on my distributor, after taking all the moving parts out of the distributor.
After some long hours, the car started on Microsquirt yesterday.
Had to design a beefier new crank sensor bracket. Thank you, thelostartof!!!
Engine bay good to go.
Injector resister, on/off idle solenoid
E85 sensor
Boost control solenoid and PCV blowby solenoid (opens at 0psi)
Fuseblocks and PC680 battery
Just need to tune now.
