I recently had the 2WSS Compustar alarm put in my car. The only problem is they didn't hook up the horn output because the installer said it would just honk all the time and wouldn't go on and off when the alarm is going off. But, befire this I had the stock upgraded alarm and that's all it did was honk the horn off an on. Is there a way to make the siren go off and the horn to honk? Also, do you know what wire I have to find if there is a way to do this?
