Default what is this? fast question?
hey guys i have a couple of questions i encountered while installing my fast 102. sorry if this has been covered but i have not seen it.

in the back of the ls1 intake their is a sensor and on the fast their is not? so does this sensor necessary or should i just leave it off

the fast has a small line coming from the back and im not sure what this is suppose to hook up too?

aslo finally when i was mocking up the fast on top of my engine in the back this piece fell off? i am wondering what is this and if its broke? i do not think i cracked it up im not sure how to put it back on

here are pics down below, thanks for any input!

First pic is the MAP sensor, it is a must have. Should be relocated on the 102 if I remember correct.

Broken piece is the oil pressure sensor as mentioned above.

Haha I wouldn't feel like an idiot, a lot of people break the oil pressure sending unit (opsu) while changing out intake manifold. You can get the opsu for about $30 at autozone. Ya, just unbolt the old opsu and bolt in the new one at 15 ft/lbs.
