Examine the area around your motorbike's handlebars and locate the ignition wiring. This consists of three different-colored wires housed in a sleeve.
Follow the sleeve until it enters the body of the motorbike through a plastic wiring cap, which will also have other wires attached through it.
Gently loosen the cap, allowing the ignition wiring to hang down.
Insert one end of your speaker wire into one of the eyes on the cap socket and insert the other end into another eye. You will hear the bike click into action, and you are ready to press the ignition on the throttle to start the engine and ride away.
