We recommend sending your helmet in for custom wiring by our highly skilled technicians, but we know that isn't always possible. We offer helmet wiring kits for the DIY option. Note there are different kits for the type of pin out (PCI, Nascar, IMSA) and the microphones and speakers are specific to use with hand held or intercom. (Motorcycle / Offroad). There is also a special kit for open face helmets with a half flex boom to get the mic all the way to your mouth for best communication.
