Hello, new here but been riding for years. Found this site and some really good stories and good info here. Hope to be around for some time. I have 2007 VTX 1300 R, purchased last year and like the bike. Has 28 k miles and runs like a champ. Installing front and rear cameras and want to power them only when the bike is running. Can I use the power wire in the headlight casing? Or is there a better power source?
