Mitsubishi Evolution X

Locate the factory boost control solenoid near the master cylinder near the firewall on the driver's side of the vehicle.
Unplug the brown connector from the factory wiring harness plugs.
Using a 10mm socket, unbolt the solenoid with the brown connector from the bracket, leaving the lower solenoid with a black connector installed.
Undo the end of the hose going to the wastegate (red end) and the compressor housing on the compresser outlet.
Remove the piece of vacuum line with red dashes from the solenoid.
Loop the piece of vacuum hose with yellow dashes from one port to the port formerly attached to the red dashed hose on the black connector solenoid, effectively blocking the ports.
Install the COBB EBCS onto the bracket as shown below.
Attach the brown connector to the COBB EBCS.
Using the supplied vacuum line, connect a hose to the port on the intake pipe where there is an existing EBCS line. Then connect it to PORT 1 on the COBB Solenoid
Using some more of the supplied hose, attach a line to the nipple found on the wastegate of the turbo, and route that to PORT 2
Next run a line from the high pressure boost source (found on the compressor outlet housing of the turbo) and route that to PORT 3
Ensure all lines are neatly routed with no kinks and away from any heat sources, use zip ties to ensure they aren't flopping around or in the way of other parts operating properly.
Flash the appropriate tune for the COBB 3-Port EBCS and you're good to go!
