Installing Stillen SC myself, need help please!

[overtureZ]

I am sure I will run into more issues but these are my questions for right now if anyone could help answer them!
First this is on a 2012 370z non-nismo
Used stillen sc kit--

1st: It came with a 25mm TurboSmart BOV, which isn't in the instructions obviously so where do I install this? with the new hoses or same hoses? Remove bypass valve, replace bypass valve, add with bypass valve? No clue, any help would be great!!

2nd: On the throttle bodies, on the stillen manifold there is a connector beside each of the 2 throttle bodies. Only came with 1 cable plugged into one of the connectors, is that correct or am I missed a cable? and does it matter which connector is plugged in if I only need 1 cable?

3rd: Are the stillen manifold bolts the same length and size as the stock plenum bolts? Because I'm not sure if I have them with the kit...

4th: Do I need to use silicon grease on the plenum gasket and injector o-rings? or just o-rings?
