4-connector
Has I & W terminals on the side for the "Electric Advance System" which works independently of the vacuum advance system.
- To 12V via thermo switch (ON when cold)
- To ECU via Throttle switch idle detect
When WARM and above idle, ignition timing is retarded. When COLD or when idling, timing is normal.
Since it retards the timing electrically, it may be useful for a forced inducation setup.
Question: If you disconnect I & W, will it still retard the timing? You can test this with a timing light.
