The pics I posted so far, pic 1 (the Chrysler 5 pin Electronic Spark Control module and harness is from a 1983 Dodge Omni. (We took spark control away from the ECM/PM stock package and it currently is set at 46 degrees static all in all the time and runs happiest at that albeit very high setting. Have tried higher and lower.

It is harder starting, but never fails to fire up. I don't know if we can even use it w/ the Terminator X..more than willing to go to an MSD based Ign. Box if not but need best suggestion on what to buy if so.

The second pic is the Bosch upright throttle body w/ the 2 wire IAC on the rear of it (I have 2 of them, a brand new 1 is on the car now, and the stock 1 I have rebuilt and the following pics are the throttle body rear without the IAC attached showing the air passage ports top and bottom. I have 1 of the original Chrysler diagnostic tools which has a function setting wherein after plugging it into the ECM diagnostic connector at the passenger strut tower you can run through 5 cycles of each EFI function like IAC, injector firing, etc.

That 2 wire IAC when running the diag just cycles open /closed so very simple.

Really just need wiring pinnout there Hi/ Low?...the Holley wiring diagram calls for 4 wires. Or do we need to go PWM?

The next set of pics is the 84 Turbo edition dual hall effect pick up distributor w/2 3 wire connectors (the 1distributo currently on the car has 1 -3 wire connector and 1 hall effect P.U. (Just top of the plate that is fired by the 4 blades under the rotor), the Turbo distro has 1 under as seen and that large 1 inside the distro body can be machined or trimmed easily enough if needed.

I only have 1 single injector and as Gump has pointed out to me we may not even need a double synch as long as the Holley ECU sees absolute TDC fir crank signal since it is single point injection?

On that distro, the pickup wires on each 3 wire connector(s) are red/green/black if the connector is cut off. The green wires are the centers w/ the white trace markings. The balance of the ]ics are the chrysler chrome box 5 pin elect. Control module and single Mallory coil.

I will get a new 5 pin connector if we can use the existing spark control module. If we switch to MSD then best unit to use I am up for recommendations before I buy it. I do want 2 step functions soon.

Next up I will find and resize and post the WBO2 pics am having issues on how to wire that up as there are 8 holley wires (7 plus the shield), then the WBO2 has actual 5 wires to a 6 pin connector-1 is not a pin. And the wire colors do not match between the shielded cable and the sensor. The 8 pin Deutch connector I will next install on the cable I have the diagram pinout locations on it, it is from the main harness connector (8 cavity),
to the 6 cavity female connector or do I need /should I buy the 8 to 6 conversion extender I saw at Summit for the 2.9 Bosch WBO2...or scrap it all and need the Holley WBO2 to solve that connection issue?

All other connections to all sensors have been accomplished. (Inputs/outputs, CAN, future dash if needed), fuel pump, relay, the main power for the Terminator X, fuses at the battery and at the mounted Term. X, MAP is internal, TPS, additional 2 Manifold ground points added & connected to the loose black main ground. Injector, Fuel Pressure, Oil Pressure, MAT, Water Temp, (engine does not have knock sensors, so those cavities in J1A were left unpopulated, plugged), car does have a speed sensor on it, I have not run anything to that sensor), I did not see any provision for that in the MPFI
