I have one installed, it is very simple.

  1. Remove the kick panel on the passenger side floorboard to get to the ECU.

  2. Disconnect the plugs going to the ECU (be VERY Careful these would be VERY expensive to replace) you may want to remove two of the screws on the ECU to release it so you can get at the plugs better.

  3. Plug the FCON harness in between the original ECU plugs and the ECU.

  4. Now, in the engine compartment, find a place on the passengers side to mount the boost pressure sensor. I used an unused 8mm I think hole on the side of the strut tower.

    Get a "T" fitting and "T" in the hose from the FCON boost pressure sensor to the same port on the manifold that your boost gauge plugs into. I am guessing that if you are installing an FCON you must have a boost gauge.

  5. Now find a place on the firewall to run the boost pressure harness wire back into the car so that it can plug into the FCON.

  6. Plug in the boost pressure sensor to the FCON, and route the FCON unit under the passengers side seat. Cover the harness wires with the floor mat and you are ready to go. If you have an air fuel meter gauge you should see that you are getting more fuel at higher boost levels then you were getting.
