Hi Folks, there has been a thread on here regarding changing the single horn to twin horns, I bought the twin horns and hopefully will be fitting them this afternoon, the roadster has twin horns, my plus 4 doesn't, does the plus 4 wiring loom have the second set of wires to connect the second horn, if so does anyone know where they are hidden?? If no second set of wires what is the best way to connect them? Many thanks (I'm useless at electricity!!) Ian
