AC VACUUM SWITCH 2571501 AND 2096084 QUESTIONS

I just ran into the same problem on a 67 Barracuda . I have a 70 and a 71 car here with the newer switch for reference. I will be working on those connections soon. Right now I am installing a map light system and switch so the 67 car has a timed key light, ashtray light,and a map light switch verses coming on with the dome light only. I'll post the findings on those three wires. Also working on installing the rear air on a fastback .
