On my micra rally car which is from holland orginally , my dials are in kph and it seems to work ok ish up the road but upon striping the car I saw that the speedo drive was not connected , and that there was another sensor ( like a abs sensor ) in the box , but this has a box fitted inline non standards I'm sure . Can anyone tell me what this is and does ? It must be converting the signal , but I'm surprised it has a speedo drive and a sensor any help would be gratefully received
