Circuit 12 must be the middle trigger point contact. The other two circuits are interchangeable. I don't think it matters, the way D-Jet operates. The trigger points initiate the injector pulse of an alternating pair of injectors and that pair gets 1/2 of the needed fuel injected the first cycle. The other half come around the second dizzy cycle which is coordinated with the engine timing.
The non-polarized D-Jet connections are: The trigger points, injectors including the cold start valve, MPS, TS1 (and thermotime switch for the 75-76 cars only).
The only polarized D-Jet connections are the ECU connector, TPS and relay board connector.
Thank you! I'm quite sure I got the middle one right!
