Short Persian-language PDF, about 183 KB, whose title translates as a tutorial for changing the colour of the Pride odometer, meaning the instrument cluster of the Saipa Pride car. It is a how-to guide rather than a full wiring diagram, presumably showing how to swap the backlight LEDs in the speedometer and mileage display. Before working on a cluster, disconnect the battery, note LED polarity and series resistor values, and check that replacement LEDs match the original footprint and forward voltage so the cluster circuit is not overloaded.
