I currently have the old style camaro wheel in my car. I am looking to put the newer wheel in it for the steering wheel controls. I already have the signal conversion for my radio since it is not stock. My question is what should I tap into for a switched power source for the steering wheel controls. I have noticed that the steering wheel control circuit runs through the SIR Coil. Since that's the case, should I then use the power from the old SIR coil? If I do, will it keep my airbag light off and is that a switched power source. Thanks in advance for any help!!!
