Hello, I recently bought a BMW 523 and e39, and it does not work in the tachometer and the economizer and the traction control and cruise control, I tried to connect the second counter from the same model, but it did not work, speedometer, fuel level and temperature indicator and other controls normally operate with with control abs, I'm not sure if the previous owner did not try to undo the counter and not to damage any electronic module, please help in this matter. thank you in advance for the reply.
