To find a speed signal for fitting a taxi meter to a 2011 Ford Mondeo, you can typically tap into the vehicle's speed sensor located on the transmission. This sensor sends a pulse signal related to the vehicle's speed, which can be used by the taxi meter. Additionally, you can check the vehicle's wiring diagrams or consult with a professional installer for specific pin locations and connections. Always ensure to follow manufacturer guidelines and local regulations when installing aftermarket equipment.

It depends on what type of signal the meter needs/ voltage range. The signal would have to intercepted form the transmission sensor, wheel speed sensor or the signal going to the instrument cluster. An alternative is to get a separate GPS based/speed sensor, auto-meter sells one to use for their electronic speedometers due to different transmission, wheel sizes combos available when a car is customized. It might be better/cheaper to due it that way.
