Well, you can hack it and just drop the wheel in. No cruise, no horn and a dead air bag sitting in the passenger side of the dash <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

The S13 hub should have allowed for the horn to work without any problems. I talked to an S13 owner and he mentioned that the momo hub was specifically made for the S13 to allow the horn to work without any modifications.
