- Black Wire: Connect to vehicle ground.
- Orange Wire: Connect to constant 12V power source (battery +) for memory retention.
- Yellow Wire: Connect to speed sensor signal input.
- Green Wire: Connect to RPM signal input (e.g., ignition coil negative, CDI, or ECU signal).
- Blue Wire: Connect to high beam indicator.
- Light Blue Wire: Connect to left turn signal indicator.
- Dark Blue Wire: Connect to right turn signal indicator.
A detailed wiring diagram showing connections to the motorcycle's electrical system would typically be included here.
4.3 Speed Sensor Installation
- Mount the speed sensor to a non-rotating part of the wheel assembly, ensuring it is stable and does not interfere with moving parts.
- Attach the magnet to a rotating part of the wheel (e.g., brake disc, wheel spoke) so that it passes within 2-5mm of the sensor head with each rotation.
- Route the sensor cable securely, avoiding heat sources and moving components.
An image illustrating the correct placement of the speed sensor and magnet would typically be included here.
4.4 Initial Setup and Calibration
After installation, turn on the ignition. The gauge will power on. You may need to perform initial calibration:
- Wheel Circumference: Enter the circumference of your front wheel in millimeters. This is crucial for accurate speed and distance readings. Refer to your tire specifications or measure manually.
- RPM Pulses: Set the correct number of ignition pulses per revolution for your engine type. Consult your vehicle's service manual if unsure.
- Unit Selection: Select desired units (e.g., km/h or mph).
