Default Knock sensor wire connector

Hi, need some help. When I pulled the intake manifold off my 06 WRX I accidentally pulled the wires out of the harness connector for my knock sensor. I fixed the connector, but I'm not sure of the polarity. I have a black wire(ground) and a white wire(5v?). Not sure which pins they connect to. Not even sure polarity matters, but would like confirmation. Any pics would help. Hope I explained my issue.enough, if not please let me know. Thanks!

White wire is pin 1, black is pin 2. Look at your crankshaft position sensor connector - white wire on that is pin 1 as well.

Thanks, pin 1 is the one on the left, looking at the harness connector. Don't suppose you could take a picture.
