olographics

Hi,I really hope someone can help me with this,I have a 2005 mazda 3 HB and recently I buy a set of mazdaspeed 3 2007 seats to change them for the stock ones,everything fitted without a problem except for the air bag sensor on the bottom of the seats,I thought the connectors were the same as in the mazda 3 seats but when I connect the white box with the new seats the passenger and driver air bag are not working because I can see the airbag light on in the dashboard and in the console.
I am afraid to go to the dealer because I know they will charge a lot of money to make the apropiate connections, anyone out there know if is there a cheapest way to fix this problem?????
I really like the new seats but I am afraid of driving my mazda without the airbags working.
Thanks a lot for your time and help
