I measured up my 8 -31 Victoria and the cables lengths are different than on the 8 -35 . My L knob is attached to a light switch , S requires 40 inches - H requires 40 inches - C requires 48 inches they all require armoured cable roughly this length with the interior wire sticking out a few inches past the armoured cable . I will trim them to fit when I install the cables . Greg Coleman is casting them directly into the knobs except the L knob which has a 6 - 32 thread tapped into the knob to accept the light switch .
Here are what the finished knobs look like.
