and not the wiring. The solenoid is just a coil, so as you stated, the wiring polarity doesn't matter. If I recall correctly, the Perrin solenoid is a 3 port solenoid. When the EBC is off and the solenoid receives no voltage, the turbo wastegate should see the pressure from the turbo compressor outlet w/o restriction, i.e. straight through the solenoid. When the EBC is on and cycling, it should be blocking the pressure to the wastegate, which lets the turbo build boost. Without any info on the solenoid itself, you should be able to find two ports that air passes through freely with no power applied. The same two ports should block air when you apply DC voltage to the coil contacts. Because it's a 3 port model, you need to determine if pressure is bled through the third port when then solenoid is engaged. If so, you'll want to plumb that back into the intake tract so you don't leak any metered air.
