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.
Then, driving the car, with the w/g controller either all the way down,
or off, it should regulate at the spring pressure of your
actuators, or about .4->.5 bar, .7->.8 with upgraded actuators..
From there, turn it up 5% at a time till you get the boost you're after
in low, then repeat this in high.
The factory gains, etc. are good for starters. You can tune the
controller for slightly quicker boost response by increasing the
gain until it spikes the boost a little bit, then turn it back down till it
does not do that. You can do the same thing with the START BOOST setting.
