Just fitted some Audi A3 half leather seats in my car, have airbags in them but the Seat wiring does not tally with the Airbag wiring on Audi A3 seats (colours), can anybody help on this, have tried to wire them up some colours match others don't, but no success, airbag light filcks off then returns permanent, when started, doing something wrong, your help is required, thanks
