I moved the locating bracket over to the far right of the bar, this gave me a clearer view of the rev counter enabling me to see up to 5000 rpm.
I could of tidied the cable better, but for now it worked a treat. Even in strong sunlight I was able to still see it.
It's location being high up meant I only had to glance down slightly to see the screen.
So yes, very happy with the way it has all worked out.
