Re: Alfa 147 Airbag light. PLEASE HELP!!
The KKL interace's default wiring is to Pin 7.
Airbag communicated on Pin 3.
Have you either jumpered the car's connector, at the rear uisng a paper clip for 7 to 3, or else add a micro switch to allow oyu to toggle from 7 to 3.
to fit the switch you'll need to desolder the current wire at pin 7 & use that as the COMMON of the 2 way switch.
The N/C can be wired to Pin 7 & the N/O to Pin 3.
personally i use the 'paperclip' when I'm working on my car.
Both ecus work on different baud rates & address so cross talk will not be a problem
