I need to change my speedo from MPH to KPH and have purchased a full set of white dial facias to do the job (no instructions included). These are lit by LEDs integral to the dial and are powered via a small transformer. I have removed the cluster and there is just one plug behind to pick up power for the transformer from as it is a digital dash, See Picture. Can anyone advise what colour wire is for ilumination and which is the earth. Has anyone done this before? would it be better to take the power direct from the light switch instead? if so again what colour wire to pick up from. Thanks in advance for any advice.
