So my boyfriend has changed the speedo dials on his corsa from a cable to an electronic one. he has managed to get everything else working except the actual spedometer and the rev counter seems to be out.
the speed sensor has been put in, 3 cables black, brown an twin coloured wire,
black to live
brown to earth
twin coloured to back of speedo
has anyone actually done a conversion from cable to electronic speedo or does anyone have any ideas??
