FD speedometer sensor problem

[Rotaryhead]

Hi guys,
 
my FD speedo does not work at all.
 
I already changed the gauge cluster, but that dosen´t made any difference.
 
I wanted to check the speedometer sensor, but didn´t found it :Hammer
 
Can somebody please post a pic of its location or at least gaive me an advice?
 
Thank you!

I think the speed sensor is on the gearbox, could also be a bad ground behind the cluster.
