Ahh my bad I was getting confused by the term 'cable' you mean an electric cable!
The cable in question attaches to the temperature sensor on the cylinder head...top right on this picture here
It seems you do not have a working PV, who knows there may even be no servo on your bike, the servo turns the power valve by means of cables and a pulley
you can see a servo (detached from the frame) here and the cables into the pulley enclosure
