MacBook santa rosa: PRAM battery connector broken - how to connect?

Hello everyone!

I have a white Macbook core2duo santa rosa with a broken connector for the PRAM battery. (The plastic connector broke.)

I want to connect the battery to the logicboard without the plastic piece - but how is the polarity of the pins on the logicboard? Where does which cable go?

The battery has a black and a grey cable.

I already connected the cables - see the picture attached. Next to the right pin is the letter V on the logicboard. Did I connect the cables the correct way?

Thanks in advance!
