Anyone running an Electronic Boost Controller?

If you have an electronic boost controller installed on your Porsche Turbo I have a couple of quick questions.

On the electronic valve, you should have three hoses coming off. (2) 6mm and (1)4mm. What do your hoses connect to? I think the 4mm is vacuum?

I had a manual boost controller and one 6mm hose ran to the top port on the wastegate. While the other 6mm hose ran to the intercooler. The bottom wastegate hose also ran to the same intercooler port. I'm not sure this is correct, but that's how it was setup.
