The black wire is the horn. Your SRS is on because the system is incomplete, you need the airbag. The airbag has the yellow plug. MINE DID NOT FIT (the plugs are different) so i did what Valet said, remove the bulb....On my TL cluster its easy on the accord cluster its a ***** its soldered on i just popped it. (This is dangerous!!! I think your airbags become useless, but the seatbelts lock when u hit the brakes hard, so this made me believe at least maybe the passenger airbag should work? I've read that No!!! The airbag system is not going to work.)
