Ok so I noticed there are three hoses attached next to the throttle area, and I found in my extensive search that one is the crank case breather (the largest attached to the engine), one sees boost (the smallest one under the TB), and the middle one is a mystery...

Where do I connect this medium sized hose? :confused:

Heres what I understand of how to connect all the little things in the KAT setup.... Correct me as needed (going to the dyno in 3 days!)

Wastegate connects to just after the compressor. (where does the top of the WG connect to?)BOV connects to vacuum source on the FPR, and is welded on just before the TB.Boost Controller is connected onto the wastegate signal line.

Do I have this stuff right? :help

You may be refering to the line that goes to the idle relays on the manifold. This is how the idle relay bypasses the TB. This line goes from underneath the TB to the right (if I´m not mistaken) into the plastic intake when NA, about 5-6 inches before the TB, next to a smaller one.

Bottom port of the wastegate just before the comp, yes. Top port is used with boost controllers, if you ain't running one leave it open. But since you are, which boost controller are u using? Manual, electronic? If using a manual boost controller, then I'm pretty sure the BC goes in this line to the side port. My SBC i-d controller uses a second line to the top of the wastegate, or at least that's what the instructions say... haven't really connected it yet.

BOV, is correct.

I'm using the Profec E-01... the instructions on the tial gate tells me to connect it to the top, but i'm still really confused about the e-01 directions...
