What do these do?????

The other two, I believe, control the air control valve which if memory serves correctly is what dumps all the air into only one rotor on de-acceleration to stop backfires.
Hopefully, someone else knows better.

the two solenoids are for the air control valve. i'm not sure what the vacuum switch actually does, but i know that it will horribly fail smog if its missing/bad
