Rear right ABS Sensor Part Number

[Podgie]

Hi there,

 I have a faulty sensor so purchased one online, happy days  or so I thought ; it arrived today but the Female connector is not compatible with the existing Male connector on my Outback? (A 55 plate H6 3.0).

The supplier rechecked his data base and tells me there is no alternative listed against my Reg and it is the correct part-

Oh no it’s not ! - Oh yes it is - Oh no it’s not! 

Now he’s asking me for the part number off the original  Abs sensor so he can source a comparable one;  hmmm, problem , there isn’t one on it.

Does anyone know this part number or where the best place might be to acquire said part number..Please!
