What connector is this...RB20det

[blues14]

I was poking around under the hood and noticed that there is a connector hanging under the TB on the fuel rail. its blue and i have no idea what its for. I was thinking mayby its a CC conncector (which my donor car did not have). anyways, if you have an idea, let me know.

That connects to the Air regulator.It looks sort of like the neck of a DR. Pepper bottle.

If you follow the air tube from the AAC valve on the back of the ITM forward to a "Tee" then go down under the Tbody its right there.

Does your car idle fine??

its for the AAC valve which should be located between runners 3 and 4.aac only works if it was wired up tho...

Carl I thought the AAC was the valve on the backside of the ITM and the Air regulator was under the Tbody.

The connector on my AAC is brown and the air regulator is blue like that.

IAC is the idle air control valve, its on the back of the manifold.AAC is the auxiarlary air control valve its under the plenum, all it is for is for fast idle when the motor is cold.

So its ok its not connected as long as my idle is ok?

saw where it connects, connected it.....the world is safe again.
