I've cut into the wiper box cover to build a housing for the heater matrix. The corner piece had to be clearanced for the wiper mechanism and the tube connects straight up to the stock air ducting so all the stock dash controls can still be used.
Fiat cinquecento heater matrix in place, note the neat positions of the connections down the side of the car.
I initially planned to fit the stock fresh air blower fan roughly in the position shown but when connecting it up to a spare battery it was more a breeze than a decent flow.
This is the polo heater blower which gave much better flow and will also be easier to mount up to the matrix.
