Rall

I have a 2009 F150 XL and the steering started to come apart. I found one on ebay, however it had the cruise control and radio control buttons on it. Mine did not have these features as it was an XL Model. No big deal I just wanted it for the steering wheel. I replaced it easy enough, but now the horn does not work. There was 1 extra wire that had no place to plug in, and it seems to be the harness for the cruise and radio controls. Does anyone know if this controls the horn as well? (Yes I checked the fuse). Any advice would be really appreciated. I can be emailed directly at allenr@nc.rr.com if you would like to respond directly. Thanks!
