Locate a suitable location for the ECU. Ensure that the loom will reach the necessary parts of the engine and mount the ECU. A mounting template can be found on the inside of the packaging box sleeve for reference. Using the provided mounting template, mount the ECU using M4 machine bolts with no more than 4mm of thread entering the ECU base when tightened. Locate a suitable location for your fuseblock and mount using two bolts or screws ensuring that vibration will not cause the fuseblock to vibrate loose. Drill or locate a 2" (50.8mm) hole in the firewall of the vehicle, pass the harness through the firewall and press fit the supplied grommet. Run the loom into the engine bay, but leave the ECU connector disconnected.
