E = Turbo control valve - regulates air pressure to the turbo
J = Turbo Precontrol valve - I believe controls the switch from primary to secondary but could be wrong. Yeah I wasn't completely right, it is what controls the air flow to spool the turbo before it actually starts boosting.

The one marked 'Solenoid Valve (Turbo Control)' in the diagram is the vacuum solenoid. Notice how it connects to the vacuum storage chamber (via the vacuum lines marked in red), and the purple vacuum line connects to the center port of the turbo control actuator. This is a smaller round solenoid, mounted on the ACV.
The one marked 'E' in the diagram is the pressure solenoid. Notice how it connects to the pressure storage chamber (via the vacuum line marked in yellow), and the blue vacuum line connects to the side port of the turbo control actuator. This is one of the big square-shaped solenoids in the rats nest.
If you accidentally swap the two vacuum lines that connect to the turbo control actuator (purple and blue in this diagram), the car will make normal boost at low RPM but low boost at high RPM (after the sequential switchover).

Because I will be putting a set of custom solenoid on a friend's FD and dont want nothing to go bad ;-).

After reading this post and diagram again. The first diagram is not quite right. Or let me rephrase this, the first diagram has some alternation to it therefore it was confusing.
Here is another diagram from the original FSM: Technically saying, I've circled TURBO CONTROL SOLENOID VALVE is the TCV (Vacuum), Where as "E" should be TCP (pressure).
And to replace the custom solenoid rack for sequential turbo should be the 4 that are circled: TCP, CRV, CCA, TCV.
Can someone please confirm this. Thank you very much!!!

Ok, I've figured how the vacuum lines should be routed and such. Now I have another problem and question:
I want to make a direct plug and play harness for these individual solenoids that goes directly into the harness. I've found how each harness looks, was wondering if someone can help me out with where to get the right connect for each solenoid? Thanks! (ECU harness connectors are the female side, I am looking for the male side)

I know what the connection look like. Have you seen the solenoid connection side? Not the harness side. (I just re-read my post above, I mean the harness side is the male side, and I need the female side which is the solenoid connection iteslf) I am trying to find out which kind of connector will work as direct plug in.
However the solenoid is only 2 blades. Trying to find a connector that will fit through the internet is hard.
I am considering removing the old harness connector and add in 4 individual weatherproof connectors and do it that way.

nvm, i've found a site where I can make my own harness @ http://www.bmotorsports.com. Just incase anyone is looking forward into making their harness and needs a connector.
