Need a definitive answer for airbag resistors

[imperial-custom]

Hi all. Read a lot of different figures when I have searched for this but I want to be sure before I buy the resistors. I have an aftermarket steering wheel and seats and when I disconnected the airbags for the seats and steering wheel, the airbag light came on. Could someone give me a definitive answer to what resistors I need? Any links to them would be useful as well. Car is a 51 plate 2.0 8v petrol AZM engine 115BHP.

Also, will the light and warning message go out as soon as the resistors are connected? Or will they need to be reset? Will disconnecting the battery overnight reset them?

Thanks in advance.

Ray.
