I have search the forums and have found a couple websites that will get the conversion half way. My problem is that I am running an Automatic trans and am trying to convert to a 12-80 ignition module. This is how I have the wires connect so far after looking at the websites and the shop manual.

The Red/Blue wire to Negative Coil

The Ignition Module Negative to the Negative Coil

Connect the Green White Wire and the Black White Wire that ran to the Ballast

The Blue Wire to the Positive Coil

The Ignition Module Positve to the Positive Coil

The Black/White Wite to the Positive Coil

That leaves me with a unconnected solid black wire. Where does it go?

Are there any errors in my process above. Please Assist. Thank you.

So far I have found that the Red/Blue wire is a Red/Black Wire that run to a relay and the Black wire also runs to the relay. So now I have:

The Ignition Module Negative to the Negative Coil

Connect the Green White Wire and the Black White Wire that ran to the Ballast

The Blue Wire to the Positive Coil

The Ignition Module Positve to the Positive Coil

The Black/White Wite to the Positive Coil

Any thoughts?

Solid black is typically ground.

By "shop manual" do you mean the FSM? The FSM has a big wiring diagram in the back and a smaller wiring diagram n the Electrical section that should show you where the wires are attached, with drawings and descriptions of what the components do. A 1979 or 80 280ZX FSM should show the E12-80 module.

You will probably find that you only need a jumper from coil positive to the module positive and the coil negative only connects to module negative. The module controls current through the coil by "gating" the flow through the negative terminal of the coil. You would only need to modify the ballast connections if you are changing the coil. But you can do that as a separate operation.

An ohm/volt meter is useful also for determining what wires are grounded and which have power. Typically there is a black ground wire from a distributor mounting bolt to ground, to ensure a good ground for the module. Your question doesn't tell where the black wire comes from.

You could also search a little more, I'm almost positive there's a write-up out there about putting the ZX distributor on an early 240Z.
