Multiecuscan

Please help me. I'm really confused. I've seen on the supported car list that i need to connect a pin 1 and 9 to recognize the abs and electric steering, but which cable i have to connect to: ex pin 1 with pin 9?? And last question: could i deactivate the seat belt buzzer connecting to visteon instrument panel of Fiat stilo 1.9 jtd instead of Bravo 1.9 mjet (there is no voice to deactivete)....
Many Thanks.
