The Honda CB Verza 150 is a popular commuter motorcycle in Southeast Asia, and its speedometer cluster combines speed, odometer, fuel gauge, and indicator warning lights in a single unit. A CB Verza 150 speedometer wiring diagram maps the connector pins for the speed sensor signal wire, the instrument power and ground feeds, the fuel sender wire, and each indicator lamp circuit. This is especially useful when the cluster is replaced or when diagnosing a non-functioning gauge after electrical work.

How do you read a wiring diagram for the speedometer of a CB Verza 150?
The CB Verza 150 speedometer connector typically carries: a 12 V ignition-switched power feed (usually pink or red/white), a chassis ground (green or black), a speed sensor signal wire (often yellow or orange) from the reed-type or Hall-effect speed sensor on the front wheel, a fuel level sender wire (yellow/white) from the float sender in the tank, and individual feed wires for the neutral, turn-signal, high-beam, and engine warning indicator lamps. To diagnose a dead speedometer, check for 12 V on the power pin with the key on, confirm a solid chassis ground, then check the speed sensor output with the wheel spinning. Always refer to the model-year-specific Honda wiring diagram as connector colours can vary between production runs.
