Can't give you a definitive answer bt don't expect the wires to be the same thickness, the heater box would have been made by an outside supplier who for their own reasons used a thicker wire.  Notice how the wiring loom seems to be very thin? with the right insulation you can use a much thinner wire for medium and high current applications (though voltage drop may be an issue).
