VSS not working 1.2 16v conversion

A question for anyone who did a 1.1MPI / 1.2 16V conversion on a Panda 141. My VSS (vehicle speed sensor) isn't working at all. The question is, is it the incompatibility of the sensor because we used a complete Fiat Bravo 1.2 16v engine loom and ECU but left the Panda's VSS (a combined sensor) or is it something else maybe. The engine is from a 2001 Fiat Bravo 1.2 16v (59kw). Any help would be greatly appreciated.

hmm crazy as it sounds, you could also ask in the Cinquecento section. i think they got the RPM gauge to work by tapping into a coil live..

Re: VSS not working 1.2 16v conversion

The speedometer was and is working now, because its mechanical with a cable. Im just not getting a speed reading to the ECU and OBD.

Re: VSS not working 1.2 16v conversion

Ok, so a little update, i found that when we were doing the conversion we severed the power supply per ignition wire for the VSS, the negative is connected, the only thing that i need now is if someone could provide me with the information which pin on the ECU is for the VSS signal? The ECU is Bosch ME73H4.
