hi, i don't know what I've done wrong but i have installed this and now non of my cars have horns, sirens or make noise when you brake or skid. I have had this in before like a month or 2 ago and it worked a charm, however this time when i installed it this happened. I have followed the youtube vid in the read me, however i don't know if it has anything to do with the .ds files as i don't know what to do with those. I have ELS installed, i hope you can help me, thanks.
