CDI/ECU Placement??? Wiring loom , speedometer

[JayStallion]

Hi all,

I have a gas gas ec 300 2004, I am currently building it from scratch. The previous owner put in over sized piston rings and blew the top. He took the entire bike apart and got fed up with the project so sold it me.

Over the years I have been slowly rebuilding it and I'm getting closer to firing the newly built engine for the first time.

I have come to the wiring loom , CDI unit and speedometer but can not find the route where the wires go and mainly where the cdi unit sits.

Can someone please advise me on the above.

Thanks in advance
