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.
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
behind glovebox on ecu 2nd plug down top wire light purple/white
Code 55= "No input signal from vehicle speed pulse generator"
is it for a taxi meter if so you are ok do not need a unit for it as i have on as a taxi
The answer is 72Km/hr
Pulse is Green/red trace behind the stereo. Remove trim from around Handbrake, then lift the trim around the handbrake, access then to two screws at base of radio facia. Remove glove box (pull sharply to disengage). A third screw, which goes into side of radio can then be removed. Whole facia, complete with radio and air vents can now be pulled forward to expose connector at rear of radio. Green wire with red trace gives a pulse of 4k
measure the pulse or ac mesuremnt on the two point result should be 1v or less
Pulse signals from what? speed sensor abs wheel sensor fuel pump pressure sensor crankshaft sensor camshaft sensor knock sensor
where is the speed pulse wire in a Toyota corolla
