Single-Wire Electronic Ignition Kit Chevy/ GMC Truck 57-74

Upgrade your classic Chevy or GMC truck from breaker points to dependable solid-state electronic ignition with this Breakerless SE Single-Wire Electronic Ignition Kit. Designed for compatible breaker-point distributors equipped with a windowed-type distributor cap, the system fits completely inside the distributor for a clean installation that preserves the original appearance of your engine compartment.

The fully integrated trigger and power module eliminates the need for additional wires protruding from the distributor. Only the original points wire remains visible. Active dwell control maintains strong spark energy at higher RPM while helping reduce ignition coil heating at idle, and automatic standby protection helps prevent coil damage and battery drain if the ignition is accidentally left on.
