!AIR question
I have in the back of my intake manifold, a piece that comes out which not only has the output for the brake booster, but also an electrical switch, to which a T-fitting is attached. One side went to this switch, the other side I know goes along the engine harness to who knows where (I'll figure it out when I put the harness back on, Im in the process of changing my engine), but the other leg went towards the driver side and I know this went into the diaphragm thing for the AIR system that took the air from the pump and split it to each bank.
Can I leave this leg unattached (the one that went to the AIR diaphragm)? What exactly is the function of this switch? If anything I could just "not plug the harness into it" if it will remain closed and not cause a vacuum leak.
for reference, this is the back of my motor here....

Thanks in advance!
EDIT- this is for a 2002 SS
