I have the solenoid on the rochester but no wire. Cant see one cut anywhere. My thinking it must tie into the a/c circuit somewhere.

I may not be correct on this one but dug through everything I have. I can't find any reference to the Idle Stop Solenoid being used on a 69. First year I see it used on was a 70. Best I can come up with. Maybe someone else knows something better.

Will have to check the carb numbers. I believe the solenoid is original. Thanks for the replies.

I agree with John. 70 was the first year for an idle stop solenoid however it was only on the 6 cyl. The first year for idle stop on the V8 was 72. In all cases 70 – 72 the idle stop solenoid gets power when the ignition is on. I think it was meant to help prevent engine run on. When the engine was shut off, the carb throttle plates (butterflys) close a small amount more to help kill a hot engine.

In later years GM tied an idle solenoid (fast idle) with the A/C to increase idle position when the A/C compressor runs.

Thanks guys
The carb isn't the original and is off a 72.
