I could really use some help with the wiring on my 92 501 berg the bike is a stolen recovered and the wirings been trashed .I intend to just have a simple ignition system with a kill switch .the question is which colour wires from the stator do I connect to the coil also what is the little square box next to coil is that the cdi unit .if so how do I connect this l so I get a spark at the right time
