hey i am havving some technical difficulties figuring out some vacuum lines on a 1990 s5 na rx7.. im installing the stock intake box and i cant figure out where the two hoses connect to... one goes to the BAC but where does the other one connect to??????

 

no one???? jesus does no one know lol

 

Pictures?

The BAC should get the air AFTER the air flow meter, BEFORE the throttle body. The other one goes to the smog pump.

I think.

Pictures?

 

Yes, pictures would be very helpful.

If you're talking about the 2 metal connections on the bottom of the black plastic intake tube between the AFM and TB, I think the 2nd one just gets left capped. Or at least it is on an S4 NA.

If you're talking about the airbox itself, there's only the one connection for the air pump inlet.

 

I think you mean these two hoses on what the FSM calls the air funnel. One goes to the BAC. I'm not really sure where the other one goes but I think it runs to the back of the engine and under the UIM. Then it connects either somewhere under the UIM or on the other side of the engine near the solenoid rack.

 

AWS is the second one
