Finally got a set of wingbacks for my RS4

Removing my comfort spec seats (with airbags) and replacing them with the wingbacks (no airbags) will pose the issue of the yellow airbag plug not being used and the dashboard airbag warning light coming up.
I've read about the resistors being put in to get around this. Where can I get the correct resistors from? My main concern is that I would not want this to affect the other airbags in the car, can anyone confirm this?
I also have a spare RS4 that previously had wingbacks in so I have access to the complete wiring loom as spares if swopping the looms are a better option?
Thanks for any advice
