Yes- - - -Ford used a resistor wire. GM switched to the same approach sometime in the early 1970s, I believe. The wire from the ignition switch to the coil primary is about 10 feet long, and doubles back on itself inside the wire harness. It has a silvery-looking conductor, and it's wrapped in fiberglass insulation.
