A3 Problem Side Airbag Connector

Hello diesel mechanics!
I have the following problem with my A3, manufactured in May 1998, Attraction trim level:
I want to install Ambition seats (4/99), but I noticed that these only have one large yellow connector for the airbag (with 3 pins connected), while the seats I have and the wiring harness in my car have one small yellow connector (with 2 wires) and one large red connector (with 1 wire).

Are there adapters available from Audi or possibly other companies to connect the seats? Other tips (like modifying the plug or something else) would also be helpful to me.
