Greddy Profec install on external wastegate

[Lucas03es]

So I have read a few threads found via searching about people installing a Greddy profec ebc unit to Tial external wastegates, but I am unsure of how it is supposed to be plumbed to my Turbonetics Evolution unit.

From reading the instructions to my turbonetics unit, and it says that for EBC installation, to refer to the EBC instructions. There is two ports on the WG, bottom is the boost sensing line, and the top is left VTA right now.

The greddy unit says to connect the "NC" to the compressor housing, and the "COM" to the wastegate.

Now, I have read that the top port on my wastegate is supposed to be connected to the "NO" port on the boost solenoid. Is this correct, or should I leave the top port of my wastegate, and the "NO" port vented to atmosphere?

Thanks for the help, and im sorry if this has been answered before, I tried to search I swear!

I use industerial solenoidson my profec (i had the old style and it's solenoid went bad) if ytou just swapthemarouind and test you'll get it.. my normally closed "out" goes to my topwastegate port, and the bottomewastegateline is "T"''d into the "NO" (or exhaust) portof my industrial unit.. this works likenormal

if i put the "T" parts into the NC or (in) port then the thing woprks backwards, the morei turn it down the more boost i get (i think i'm going back to that for more reliable boost levels as well as higher ones)

Alright, well I will just hook it up and see how it reacts with the different lines hooked up. Thanks again, Glenn.

Ok, the more forum posts I dig up the more it starts to make sense. OP, what setup ended up working for you? Glenn, which setup did you stick with? I just posted a diagram of what I gathered from reading up and viewing other diagrams. What do yall think? I think it is exactly as you describe in your first option Glenn. Here's the diagram, thanks in advance: http://www.dsmtuners.com/forums/electrical-tech/440233-ebc-ewg-install-help.html
