My understanding is that the 'magic box' that is needed (and can, indeed, be bought off ebay for around £30) has nothing to do with CAN buses and is simply a 50p 555 timer in a box set up to provide 12V square wave signals meant to represent speed and engine rpm. Their principle drawback is that the signal frequency is fixed - tho variable using a manually adjusted pot - but once you've set it the amount of assist is fixed. Less than ideal but workable.
Best write-up I have found yet on this is here... http://www.super7thheaven.co.uk/blog/corsa-c-electric-power-steering-epas-a118.html I should say this is all relates to Vauxhall Corsa B and C models so the Ford Fiesta may be CAN after all.
