Eberspacher connector?

[Ian_Edwards]

I've just bought a second hand Eberspacher hydronic 10 off ebay, to replace a dead one currently installed.
I looks OK in reasonable condition, but the connector which interfaces to the outside world has been removed.
It is referred to as S1 , and is connected the external wiring loom through B1.
I'm struggling to find a replacement connector S1.
B1 seems to be readily avaliable, but not the matching part S1.
The wiring schematic show 3 rows of pins, top 3pins, mid 4pins, lower 5pins, plus 2 larger connectors at the bottom.
Any Eber experts who can tell me the part number, and possible place, I could buy one?
I've tried the Butler Technik website and a general Google search, but no luck so far.
Cheers
Ian

Is S1 the socket? If so, check the spare parts manual at Butler Technik - https://www.butlertechnik.com/downloads/Eberspacher_Heater_Hydronic_10_Spare_Parts_manual.pdf

No, the part labeled 2, is B1.
It's the other half, which is in grey and not numbered which is S1, I guess ìt's a plug.
These are probably generic parts, I don't think Eberspacher will manufacture their own connectors.
I'll try phoning Butler Technik and others tomorrow, when I get a chance.
I'll also try and get a photo of it, but it is under the cockpit floor, and you have to be a contortionist to work on it.
