Does the solenoid have two or three nipples on it? Also are they marked 'IN' and 'OUT' or just numbered?

You should have the three port solenoid.
For the factory turbo with internal wastegate--->
Looking at the solenoid with the middle port further away from the two outer ones. The first one on the left goes to intake manifold vacum. The middle port goes to the nipple on the front of the turbo. The third one on the right goes to the nipple on the wastegate actuator.
The first one on the left must be connected to a source that has manifold vacum. For example where the fuel regulator of blow-off valve hose is connected to.
Also some applications have a solenoid connected between the fuel regulator and manifold. Make sure and tee into the side of the solenoid that goes to the manifold.
If all that is too confusing then try this-->

Check above now

 

got a question what happens if i wanna run external wastegate later when i go big turbo????

and thanks for your help

also i have one in the back where does that one go??

The diagram above in the link shows how. Remember to check the dip switches in the back of the controller. You must set that up for internal or external wastegate type.
As for the fourth nipple I have no clue. Probably just a vent for the solenoid case.
Greddy's website does not have what you need either. They only have the first part of the instructions or part 1. By the time they put up part 2 we all will be driving souped up electric cars!

 

ok i just did that umm but in the website it only shows 3 nipples??? i have 3 nipples in the front and 1 in the back im lost where the one in the back goes??? and last one is the solonoid box supposed to make a constant clicking sound???
Thanks again
TwEaK

correction just re-read what you said so ummm should i just leave the back open or??? lol im lost =)
TwEaK

 

Sometimes they do especially the early ones in the metal case.

 

One way to find out.

 

o ok yea thats what i got i mean hey for free you cant lose lol ok so i understand... so i just leave the back open and see what happens???
TwEaK

 

crap you post faster than i can read lol..... ok i appreciate everything chris ill let you know what happens
TwEaK

P.S one last thing does it matter how many times i T off the upper intake manifold vacuum/boost??? im already T off once for the boost gauge and BOV.. would it hurt to T off twice more for the wastegate and for EBC?
TwEaK

 

What do you have from the wastegate teed into the manifold?

 

o no i havent put it on yet.. but was planning to i was told the top feed goes to boost controller and the side feed goes to a vacuum/boost source

Hope this helps
