We are hooking up the horn ring on a 16' Interceptor sedan. We cut the loop and inserted a wire and ran it to the horn ring connector on the 295SLSA6. As soon as you turn the siren controller on it activates which is obviously wrong. Do I need to separate the wire and run it two different places? Sorry for the lack of knowledge but I appreciate the help in advance. Our shop does our installs in house and they've never done it before.
