install taxi meter on volvo s80
you need to buy a CANBUS INTERFACE
on the back of the stereo . middle plug green wire with white trace
the middle wire on the speedo block on the engine by the gear lever in the engine
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.
To obtain a speed pulse you would require a CanBus Unit and connect it to the correct can wires. Usualy the OBD 2 socket. Pins 14(can low) and 6(can high). :)
behind glovebox on ecu 2nd plug down top wire light purple/white
Code 55= "No input signal from vehicle speed pulse generator"
The speed sensor and the ABS sensor are combined on a 6 speed Mondeo TDCI. It is located above the OS driveshaft.
