You don't have to have the coolant lines connected to have the BAC work. All you need is the line from the intake duct and the wiring.

It has been too long since I saw a stock TII I can't remember if it comes from the back of the engine or from the front of the engine, sorry. Although I can tell you that it likely is connected between that coolant port at the back of the engine and the coolant port on the back of the water pump housing.

You could check the engine section of the FSM.

I think the Air Bypass solenoid only operates right after initial startup, while the BAC operates all the time.
