Hi Steve, if your steering head has a half or full gusset plate around it, then you should be able to feed the cables inside, so they exit out the top on one side. Just make sure that when you turn the steering to full lock, that the cables aren`t stretched, you should end up with a slack loop in the loom (between steering head and headlamp) when pointing straight ahead. Hope that helps Rich.
Here you go Steve, easier than trying to describe. That`s with the steering on full lock to the right, cheers.
