ergo350z

[B]I have a 2005 350z, a while back I had a shop install a sport steering wheel, one of those that easy snap on and off. at the time I notice the airbag light was on, after the installation, the Tech told me that it was normarl, since the new steering wheel did not have an air bag. recently I got tired of having the air bag light on the dashboard, so I decided to install the factory steering wheel, well, here's the problem I notice that the wires for the Horn and the Airbag were missing and I couldn't find where they're suppose to come from. the freaking guy cut the wires off and left no trace where they were. can any one point me in the right direction or tell me where I can find a picture that shows the wires. currently I don't have a horn, the horn is theres because every time you lock and unlock the door it sound. I just don't have the two wires connectors in the steering wheel. HELP
