Throttle cable routing

[Raynsford5]

Hi all I've pulled the plastic tube from under my van with the intent to lubricate it as the cable seemed stiff, I now have an issue as I didn't take photos of the tube route the cable does not reach.  I think it's the tube routing as the tube reaches to the 2 locating holes by the peddle but the cable doesn't reach the clamp and if it does there is no slack at the engine end. Does anyone have a diagram of the tube routing.
Thanks
