Installation kit
MXL Plug&Play kit for Subaru Impreza guarantees the maximum ease of installation.
2.1
MXL Strada/Pista kit installation
MXL Strada/Pista is not internally powered. This is why you have to connect Subaru interface wiring
free cables to a +12 volt power source connected to the ignition key switch so that your MXL switches
on/off with the vehicle.
MXL connection with the ECU is made through the OBDII diagnosis plug placed under the steering
wheel column as pointed out here below on the left. The image on the right shows the OBDII plug
where the dedicated connector of Subaru interface wiring is to be plugged in.
