Wiring colours don't match

[waynedear]

The old 05 BMW intelligent battery sensor has 3 wires coming from it... Red, Grey and a blue+white.
The new Hella replacement sensor has 3 wires coming from it... Red, Black and Green.
Red I know where that goes (positive terminal)...
Black and Green to the different colours I don't know. 😖
Any electrickery wizards

Playing devil's advocate.- Just because two of the colours don't match, don't assume that the one colour that does match is right.
Contact Hella to confirm. After all, most companies won't accept returns or complaints on electical components.

Thanks for that, I am 100% on the red, the connector end going to the loom and splitting into two paths is in a single and double piece.
UPDATE, done 😁, still have the same issue so on to new search.
