Reply to "Sticky #2: First Time Purchasing Advice & What Are The Essential Improvements"

With the breaker point ignition the voltage supplied to the ignition coil during normal operation passed through a ballast resistor which more or less dropped the voltage down to about 50%, the coil operated on about 7 volts.

The orange wire temporarily supplied the ignition coil with full 12 volts (no ballast resistance) during starting, to help start the engine quickly. If a 7 volt coil is supplied 12 volts full time it would quickly fail due to heat, but for a few seconds during starting its OK.

Since your new ignition runs on full voltage full time, the extra wire to boost starting voltage to the ignition coil is unnecessary.
