Hiy everyone does anybody no on a uk zed tt manual if the speedo should read 160mph or 180mph,many thanks Mark

Thanks for reply,Jeff posted me a diagram of where they go,but still doesnt explain why i have blue coming from sensor into engine harness and somewhere changes color to yellow/green at clocks and everything looks original,but no continuity from blue to the yellow/green.So without undoing the harness which is a last resort i might just connect the blue wire to a new wire straight to the y/g from clocks,cheers.
