Figure XXIII shows the wiring diagram for the MV Airo 5. The
wires of the main heater have been made into bundles. They can be laid
according to the positions of various components and should be fixed to the
proper locations. The distance between two fixing points should not exceed
300mm.
Note: Any exposed wire outside the vehicle should be protected so as not to
be ripped by any road debris etc.
Gently remove the Airo 5’s junction box cover and insert the main connector
of the wiring harness into the E.C.U. at X7 (figure XXV). WARNING: The tab on
the main connector should be facing upright when connected, as the E.C.U.
will become damaged if plugged the incorrect way in. Next connect the
temperature probe plug into X5. The loom can either exit to the right, or left
of the heater body, depending on preference. The junction box cover can
now be replaced into position, ensuring the rubber grommet sits neatly in the
cut out of the ECU cover.
A bladed fuse will already be inserted into the holder ‘F’ (20A for 12V versions
and 15A for 24V). Use a screw to fix it in a suitable position on the vehicle.
Connect the 2.5mm² red wire and the 2.5mm² brown wire in the wire harness
to the spring terminals and then to the positive and negative of the vehicle
’ s
battery.
Straighten the fuel pump leads (two 0.6mm² black wires) and put them
through the opening on the wall of the combustion air inlet pipe of the
heater. Then insert the plug to the spring terminals of the fuel pump
connector.
