What if your 1990 s13 speedometer isn't working so you got a jdm one how do you transfer the odometer and 220kmh dial face over and make the jdm one read up to 220kmh?

To transfer the odometer and 220 km/h dial face from your original 1990 S13 speedometer to a JDM unit, you'll need to carefully disassemble both speedometers. Remove the odometer mechanism from the original unit and install it into the JDM unit, ensuring that all gears and connections are properly aligned. Next, swap the dial face, making sure to align the needle accurately for proper readings. Finally, reassemble the JDM speedometer, ensuring all components are securely in place before reinstalling it in the vehicle.
