Hey man nice build. You will probably benefit from my build thread in the sig. As stated, you don't need those brackets for the intake, WC's just a cautious nub! Weight savings ftw. The hose coming off the bottom of your TB is the coolant hose, there are 2 of them. Don't bother hooking them up, they'll warm up your intake charge. This is only good for warming the motor up marginally faster, and spoils what your intercooler is for!
Also, don't hook up the coolant lines to the IACV/idler as this will do the same and is pointless as to the running of the car. Cooling temp sensor tells the ecu what the temp is nothing else.
I went over what I did for my cooling lines in the sig also.
In terms of vacuum, the big tube w/ the screw in it is for your BOV. The smaller vacuum probe is for the FPR. The tiny 90 degree bent vacuum probe on the bottom of the TB is for the charcoal canister and is not needed, plug it. Do not hook up a boost gage or FPR on this nipple as it does not read vacuum when the TB is closed. You might note why, it leads to a hole that ends up before the throttle plate. This hole is only good for maybe an HHO intake setup, as it only works when throttle is depressed.
Should get u started. Good luck building and prepping a motor is one of my favorite things to do!
