The following steps outline the installation procedure:
1.Ensure the key is in the OFF position and remove the ECU from the vehicle. The factory ECU is located in either of the following places: GT-X - behind the centre consol, MX-5/Miata - under the passengers foot well carpet. Unplug the wiring harness from the factory ECU. Remove the 6mm bolts (10mm socket) that retain the ECU and remove the ECU from the vehicle. DO NOT touch the exposed pins in the factory ECU connector.
2.Remove the factory ECU's circuit board from its enclosure: Ensure you are following the given anti-static guidelines and ARE WEARING A CONDUCTIVE WRIST STRAP connected to a conductive working surface. Remove the top cover by removing the side retaining screws. Remove the circuit board by removing the corner screws. Hold it only by the plastic header and place it aside.
3.Connect the ECU USB tuning cable and the expansion loom to the Link Plug-In ECU if required.
4.Fit the Link Plug-In ECU: Place the Link ECU on the base plate and carefully fit the four corner screws. Place the factory ECU in the packaging your Link ECU came in for its protection.
5.Refit the top cover: It may be necessary to widen the slot around the main header to allow cables to exit. Ensure that any modifications are de-burred to prevent cutting into cable insulation.
6.Reassemble the enclosure and fit the ECU back to the vehicle.
7.Connect the ECU to the factory wiring loom.
8.Do NOT attempt to start the vehicle. Proceed to read through the remaining sections of this manual first.
