Hello people, i need a little help please. Friend has got a 1999 nissan stagea rs4s. And horn isnt working. I had a look and couldnt find a problem. I then took steering wheel off. (Unpluged horn and airbag plugs) and was realy easy to remove steering wheel. And in picture , it shows 3 wires have been removed , and 3 wires are sitting there (which seem to be horn). And was wondering if anyone had picture on the wiring? Thanks a lot for your help.
