the one in Red is the AC cycling pressure switch connector.
the one in yellow is the Low Vacuum sensor that turns on the Brake warning Lamp when you loose Vacuum.
right now I'm not sure about the 2 pin connector.... let me look it up EDIT: self test Connector
EDIT 1 more time .. that connector may be for Tach sensor.

so a question I’m wondering is if it’s something to do with the tach, since it’s not plugged in wouldn’t my tach not be working?

so IF it is not a Tach connector the only other thing I can think of off hand is an ABS sensor Test Connector.
It is 2 pin right not 3 pin ?

luckily my tach is working properly. Let’s say it’s the ABS sensor test connector then it’s supposed to be unplugged? And I’m guessing it gets plugged in to test something to do with the ABS?

the Vacuum sensor is 3 wire.... if that connector is 2 wire and is in fact ABS test connector (Still Guessing) then it connects to a plastic cap mounted on the fender well (Generally) it would be used to just read the VSS signal with the proper test equipment.

I just looked at the wiring and it seems like the ac plug you identified has two green wires with a purple stripe. This other plug also has a green wire with a purple stripe. It seems as if they both are using that green wire with a purple stripe. They also both have a black wire with a yellow stripe going to the plugs. Could they both be AC related?
