I am hoping to avoid a visible ballast resistor in favor of an almost invisible length of resistor wire, but cant seem to find it. i was just going through a Blue Streak ignition catalog from 1972 and don't even see it listed.....
To get the right voltage drop from a piece of nichrome wire, the wire needs to be about 10 feet long. The wire from the ignition switch to the coil on the mid-1970's GM vehicles actually doubled back on itself inside the wire harness to get enough length for the proper voltage to the coil. The right wire also has heat-resistant fiberglass insulation.
