The engine shut off while driving (no restart) and that lead to my diagnosis that coil failed (no spark, ohms out of spec, casing shows sign of arcing/heat damage). After replacing the coil and spark plugs, I realize I hadn't taken a pic of the wire connections within the distributor and didn't have them in correct location (no start). I then realized I had more available connectors on the ICM than wires to attach. I located a wiring diagram and the unattached connector is the stand alone on the ICM (closest to the coil). A wiring diagram shows that to be the 'blue' wire for RPM indicator (but is that correct?). Pix/diagrams seen online show that blue wire is in a 2-wire black insulator with the black/yellow wire (power). I have no blue wire. And it's not broken off and within insulator. I can't find a blue wire inside the distributor at all.
So is there a wire that should be attached to that stand alone tab on ICM and why isn't it there in insulated wrap ('harness') with power wire for coil ready for me to snap on.
This isn't my first time under the hood. Removed heads for valve job -and that was 35 yrs ago. But I admit I'm looking silly with this Magic disappearing wire act.
Pic 1 Shows distributor wired as best guess and the unattached tab on ICM just below center of pic. (Distributor mounted)
Pic 2 Show more wiring detail. Wire disconnected from coil + terminal. (Distributor dismounted)
have the same problem?
