Need advice on 93 911 tunr signal/wiper switch/air bag

[Adidas]

Need to replace the turnsignal switch on my 1993 911. I understand that the turnsignal and wiper switch are one unit on this car and the airbag is installed in steering wheel as well. Any advice on replacement or any tech articles available. I've replaced many switches on earlier 911's but none with airbags and computer set-ups. Any advice appreciated. Thanks Bill
