Adding some research into further wiring diagrams. Some were collected directly from the Service Manual I have (and both of the models 84 2.2L TBI Z model as built wiring diagrams and the 84 Turbo Edition). As I have both distributors available. And I have noticed that the Shelby edition of the TBI and the Turbo Edition did have a Detonation Sensor in the top rear of the Valve Cover (I could certainly add 1 as the sensors are available, and I am using the Turbo Valve Cover, so I could add a bung to it easily enough).
Adding the appropriate wiring at this point to the harness would not be difficult either if it would help the Terminator X in tuning later. Are Detonation sensor and Knock sensor interchangeable in The Holley nomenclature? I am assuming they mean the same thing of course.
The single plate EFI Distro P.U. wiring connector is seen in the E.F.I. (right side, 3 wire round connector in a triangular pattern), and on the EFI Turbo P.U.'s (2) it shows up as 2- 3 wire round connectors, each keyed differently in the connector housing shape internally as 2- in a triangular pattern a little more left on the right page. I also took pics of both the key switch and fuse box wiring diagrams, and the speed sensor (I know this can be very confusing (multiple wiring diagram images but, there are multiple distro choices, as there are multiple Ignition choices), I am just looking for the choices that boil down to working out the best.
I also took a few pics from a couple of sources of the crude hand drawings (and better), of the 3 types of historical Chrysler ignition using the large type ballast resistor (mine does not have 1 unless it is very hidden somewhere). And my Chrysler Ignition Module does not have the usual external transistor mounted on the cover. I have reviewed an online resource on YouTube to test the module, coil, etc. using a test light, meter, and external old school spark gap tool.
I am posting the wiring diagrams now that I resized 800 X 400 pixels below in case they help us get the 12V switched connected to the best source under dash (or elsewhere), so we can see the 3 wire and 6 wire different distro plugs, the optional Detonation sensor choice, and optional Speed Sensor 2 wire connection/routing (though I do not know if there is even Holley Terminator provision for that at all...Possibly input/output? Or if it would even add anything to the equation, but it exists).
