Hi David.
Nice work I presume you have used the two wire 2 speed from the petrol fan, using the fan motor and it's two wires red and black then rewired it incorporating the gold resistor to the original diesel control box, doing some wiring changes in the diesel control box also.
Hopefully you also kept the relays from the petrol control box as they always come in useful.
I would not want to take my car to whomever did that bodge job for any sort of work, again well done cheers Arctic.
