I read this over on the Electric section of the forum, but I'd ask there to be sure. Subject is a 69 truck so not directly applicable.
I'm sure VetteVet will know.

Next is the cloth covered wire that started life as an orange/purple white wire that is a resistance wire to protect the ignition coil from overheating during normal running. It drops the ignition voltage to approximately 8 volts to the positive side of the coil. It joins a yellow wire which goes to the I terminal on the starter solenoid. This I terminal sends a full 12 volts to the coil during starting for a hotter spark while the engine is cranking.
