Ignitor plug has black-red wire, black-orange wire, black-blue wire, black-yellow wire & a solid black wire. My question is..... is the solid black wire ... a ground or a signal wire. I know that the other 4 wires goes to the ECU & battery+.

Where does the solid black wire go???

Your timely response & any information will be greatly appreciated.

Assuming your B-O is really B-W (to the ignition coil), the B (if you have M/T) is the tach wire, to the combination meter and data link connector.
