I will be using a separate horn than the factory horn. It will be mounted on the bottom of the floorboard right next to the relays I use. I was hoping to hook it up tonight but my BIL grabbed Rita today to look at what's going on with the transmission. We were going to take it to Cruz to the woods by Des Moines Iowa, I was going to be danged if I let that thing sit at a motel parking lot overnight in Des Moines without an alarm, the club, a kill switch, and my concealed carrying permit LOL
