2. Remove the trim panel and keep it for future use. Remove the tachometer and cover it again. It is beautiful. Pull the instrument panel in a straight line towards the body and shake it slightly left and right to remove the instrument panel. The tachometer and clock plug shall be wrapped with white tape.

3. Use iron wire to lead the tachometer plug to the instrument panel and plug it in. The tachometer rotates and stabilizes between 800-900 revolutions, indicating that the instrument is in good condition. Replace the instrument panel and the two screws just removed.

4. Screw the screw into the reserved position between the tachometer and the clock with a screwdriver, and fasten the cover plate.
