Hey folks.

I have been trying to find an explanation of how to setup vacuum lines with the setup I have but they all seem to differ somewhere.

I have a 3 port ebc, the instructions say to connect one to the
turbo compressor housing and one to the waste gate, the other vents to atmosphere.

My intercooler pipe before the throttle body has a nipple and also there is a blow off valve with a nipple.

I think that I'm supposed to use the intercooler pipe nipple in place of the compressor housing to the ebc and just block of the nipple on the compressor housing?

Where would I connect the nipple on the blow off valve to?

 

Ideally you source your boost pressure pre-throttle body, read this thread for an entertaining explanation:

As for which port goes where, I always refer to the attached diagram.

The blow off valve vacuum barb needs to be source POST throttle body.

 

I'll post a couple pictures of my FM kit install. This is a 93 B6, There is no nipple on the charge pipe.

Here's how she looks
WOW, that's a big friggin picture

It's on a tee after throttle body
I'm pretty sure the "nipple" on your pipe is for Temp. sensor
