hi,

i am currently working on a navigation product which i am going to mount on a doblo commercial for testing pruposes.

i will need to tap out the vehicle following signals:
1. speed sensor signal/odometer signal - i know in most vehicles, these are usually hall sensors used to send pulses to the ECU to keep track the number of wheel rotations.

2. reverse signal - When the vehicle is put in reverse gear, is there a signal that will be triggered? i need this signal so that my navigation product will know if the vehicle in moving forward or reverse.

i will greatly appreciate any help on above, pictures/wiring diagrams/ECU docs, if any, will be best.

thanks

what year doblo?

sorry i am not sure which year is it. how can i check out which year is it?
