had a flat bottom steering wheel lying around catching dust , so decided to fit it over the weekend to find that my wiring off the mfsw airbag doesnt match the fbmfsw airbag . ive had a search and found off other posts that i need part number 8j0 971 589 b , so went to tps to order one and told me that the part number has changed to 8j0971589h . i was wondering can anyone confirm if this is corrrect, before i order one .
