BAC valve what is it for and i cant find a connecter for it can i leave it unpplug

 

Hey! Sorry I couldnt get up there today. Someone broke into my neighbores house and apparently tried ours too, dint get asleep till 8am.

The BAC is the Bypass Air Control Valve. Its a fine idle adjustment. The connector should be square and on the same harness for the O2 sensor .

 

thanks i almost got it done but i dont have the stock bov that comes with the motor have to hunt for that i will talk to dan monday
