Intercom wires to seperate

[djh3]

OK so the spark plug buzz in the intercom came back again. Have not had it in a long time, but just showed back up yesterday on a ride. So I guess I'll pull the gas tank and see what I can do. But which wires do I seperate from what and how? Should I use some zip ties and fuel line or something and make spacers to keep apart? Wife also complained about not being able to hear stereo very well or intercom so kind of wondering what the heck is going on.
