I’m only using the airbag light from the non-JBL unit. I’ll be using my Kenwood as the new source, bypassing the OEM amp completely. On the non-JBL radio the passenger airbag light gets removed and installed into the dash kit when you replace the radio. On the JBL radios the airbag light is part of the circuit board of the radio and cannot be removed without really hacking up the original. Without that airbag light plugged in the car gets all confused and throws error codes. This way by using a donor airbag light I should be able to replace the radio without throwing codes.
