I did the difficult bit by replacing the steering rack but now after the refit the air bag warning light comes on and horn isn't working. Considering the steering wheel had to come off to replace the rack you'd think it was a lose or poorly remade connection somwhere but I can't find it for the life of me. Does the airbag have to be reset somehow, am I missing something obvious? Did a quick check of the fuse box, nothing untoward.
