Question for NumberDummy
D7AZ-12250-A .. Resistor Wire-Ignition Coil (Motorcraft DY-213) / See 1980/89 truck parts catalog pic below.
49" long / Color coded red with green stripes / 1.30-1.40 ohms resistance / #16 gauge wire.
Applications: 1977/79 some FoMoCo vehicles, and all 1980/89 F100/350/Bronco/Econoline & FoMoCo Passenger Cars.
The wiring diagrams in my Haynes manual clearly show the resistor wire in the 1980-1986 diagrams but I can't find it indicated as a resistor in the 1987-1989 diagrams.
Is there a resistor wire in my 1989 F250? I trust your knowledge more than the Haynes manual. I'm asking in this forum because I am transplanting a carb'ed '84 351W into an'89 F250 and am trying to figure exactly how the wiring should be done.
