The following steps outline the installation procedure:
1.Remove the factory ECU from the vehicle: Ensure the key is in the OFF position. The factory ECU is located behind a black panel inside the engine bay on the firewall. Unplug the wiring harness from the factory ECU and remove any mechanical fasteners holding the ECU in place. DO NOT touch the exposed pins in the factory ECU connector.
2.Remove the factory ECUs 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 carefully bending the locking tabs back. Remove the factory circuit board from the bottom plate by removing the retaining screws holding the heatsink down and releasing the plastic clip holding the board in the centre. Hold it only by the plastic header and place it aside.
3.Remove the plastic clip from the centre of the case.
4.Remove the Link ECU from its packaging and place it immediately on the factory bottom plate. Place the factory ECU in the packaging your Link ECU came in for its protection.
5.Secure the Link ECU onto the bottom plate of the factory enclosure using the factory screws.
6.Drill two holes in the top cover of the case, one for the vacuum line and one for the tuning cable. Thread a length of vacuum hose through the hole and connect it using a cable tie to the hose joiner on the small length of vacuum hose attached to the Link ECU. Thread the tuning cable through the second hole.
7.Connect the ECU to the factory wiring loom.
8.Secure the ECU back in the vehicle using the factory fasteners and install all covers. Extra holes for the tuning cable and MAP hose may need to be drilled through covers.
9.Connect the vacuum hose to a stable manifold pressure source. It is important never to share a vacuum source with devices such as mechanical boost gauges and blow off valves. Teeing into the fuel pressure regulator vacuum source often provides a good pressure reading.
10.Do NOT attempt to start the vehicle. Proceed to read through the remaining sections of this manual first.
