    The wires on the other side of my red and black wired plug are black, black/green, black/green. I tried tracing where it goes, but it just disappears into the harness. Without taking things apart on mine, I canít give any more info.

    Do we have a thread on loose connectors? I see questions on these all too often.

    Iíll clarify that white floating connector with Black/Red wires.

    In the Early 81ís, that was used inline between the idle micro-switch and the Vacuum Solenoid. It is on the wire diagram as shown here.



    Later 81ís had an engine wire harness revision that delated the BU (Black/blue) wire with mating connector. (Btw the wire is mis-colored Blue /Red in the diagram) For some Unknown reason DMC integrated the RF Filter in the other engine bay harness but never removed it from the production design of that harness.

    Hopes this clears things up a bit.

    I remember finding that capacitor on the back side of my bulkhead connectors when I put new pins in my connectors. But the capacitor was wired to the wrong side of the wire to vacuum solenoid. It was wired to the 12 volt side rather than the switched side. So the capacitor did nothing for curing the inductive spike in my case. That spike would fire the ignition and thus cause my RPM relay to re-prime if you hit the gas without the engine running. Some cars had that capacitor mounted near the idle switch on the mixture unit.
