DIY Greddy EBC with External Wastegates
#17
The stock boost solenoid must be COMPLETELY removed from the system. The vacuum hoses should be capped or rerouted so you have no vacuum/boost leaks. The Greddy unit for internal wastegates will run the NO and COM ports. The instructions for the Greddy unit are very easy to follow for internal gates.
I will work on a drawing for you.

I redid the one for the external wastegates. Either you can use it, make fun of it, or pass it on. I believe this is all correct. Someone let me know if they think other wise.

Thanks Dan
I have the exact instructions here :-

Disconnect the factory vacuum lines from the wastegate solenoid.
Connect the NO port to the port off of the Y-Pipe just outside of the throttle body.
The COM port should go to the line that runs up over the manifold and T's off to the w/g actuators.
The NC port should go to the line that runs towards the drivers side of the car, then to the rubber pipe that holds the diverter valves.
Be sure that all the little red plugs are out of the solenoid!

Tee off the fuel pressure regulator vacuum line and route the hose along with the w/g controller harness.
Route the wiring harness forwards, just to the left of the oil tank, tie wrap the harness to the factory hose routings along the way.
In the tunnel, just in front of the grommet that the shifter/ebrake cables go through, there's a 1" diameter grommet.
You can route the harness up through there.
We typically place the controller in the center compartment where your right elbow would go, leaving about 14-16" of cable to pull
it out and adjust it, then put it away when done. But you can mount it where ever you'd like.
The hot/ground for the w/g controller can be taken from the power window switches. In the 2001 models, the ground is a Brown wire
on Pin A3 of the window switch and the key on hot is Brown/Green/Black and goes to pin A4. Be sure these are 12v and ground, we've found
a lot of discontinuities in the cars.
