Hey guys
I'm in the process of installing this EBC into my S14.
This:

The wiring is a piece of cake.. But I'm stuck on how to set up the solenoid.

The solenoid has 3 nipples on the top and 1 nipple on the bottom. The top 3 nipples are illustrated in the following picture:

But i cant seem to find anything on that one nipple at the bottom of the solenoid. This picture shows the bottom nipple:

I hope some of u have installed this EBC before and would share your knowledge/advice on this EBC with me :)

Thanks in advance

Have u tried looking on the greddy website to down load the manual

Thats the first thing I did sir. I even sent them an email.

I only could get my hands on 1 manual. And thats the manual on how to set it up when it's already wired in and connected.
But none on how to connect this and that...
