I have a Citroen C1 and it's a very basic model. It doesn't have a rev counter but I can add one because it has the cable and plug for it already exists, it's just not plugged into a rev counter. What I was wondering is, does anyone know if the plugs that feed the dashboard to provide speed, fuel level, mileage and warning lights fit in other dashboards? Basically, are the plugs standardized?
And, do all ECU's calculate MPG and just not display it on the dash or do they not calculate it and it's just specific ECU's?
