Height sensors pinout

Hi guys, can any one please post some info about the pinout of the 3 pin height sensors?? I know they hall effect sensor and tracking what should go where is a bit pain.
Could you please give diagram etc.
the info i have so far is that:
Pin1 - earth
Pin4 - signal
Pin5 - power.
however, i stripped one apart and for me looks like pin 5 should be ground as its connected to the pcb plan. but i don`t want to take all 4 apart to confirm that they are the same.
Also are the 5V or 12V sensors??

Thanks for any help

C0654 on the SLABS ECU

Pin 1 Left hand supply yellow tracer sensor pin 5
Pin 2 Left hand earth blue tracer sensor pin 1
Pin 3 Left hand signal red tracer sensor pin 4

pin 4 Right hand supply green tracer sensor pin 5
Pin 5 Right hand earth orange tracer sensor pin 1
Pin 6 Rght hand signal black tracer sensor pin 4

Get hold of a copy of RAVE if you want this sort of detailed info.

Forget to mention that all 4 sensors have only pin 1,4 and 5 and they are for disco 3. Sorry for posting in disco 2 section. Was unable to change section.
Any info on that one?

Ok guys so i`ve made my research and i`m posting results for you.( or you already know that )
Sensor numbers:
AH22-5B732-AC PIN 5 = 5v, PIN 4 = SIGNAL, PIN 1 = GND.
AH22-3C097-AC PIN 5 = 5v, PIN 4 = SIGNAL, PIN 1 = GND.

BH22-3C097-AA PIN 5 = GND, PIN 4 = SIGNAL, PIN 1 = 5v.
BH22-5B732-AA PIN 5 = GND, PIN 4 = SIGNAL, PIN 1 = 5v.

So keep in mind that opposite polarity might blow this little microcontroller as happened to me.
