I have an android 10.25 inch head unit I wish to install.I started the install today but before installing properly checked it worked ok which it was.However I ordered a cable as mine has the hazard button and passenger airbag light.Has anyone fitted one of these as unsure how to connect it as there two sockets on cable I had to order one to the hazard switch and one to the airbag but only one socket.Do i just connect the airbag one like i have in the picture but dont understand why there are two.
