My speedo drive is on the drivers side and I've decided that the best way to route the cable to the speedo is to loop it under the gearbox, just behind the bellhousing and upwards on the passenger side of the gearbox. This helps out with the excessive length and also avoids the clutch release arm and petrol pipe etc.

As long as it is clipped so that it can't hang down, can anyone think of any reason why this should not be done this way?

Also do cables have to be clipped every 300mm?
