Nordstrand NJ4SE with Audere JZ3 wiring question

[hack]

Guys,
I've just purchased Nordstrand J pickups NJ4SE to go with also recently purchased Audere JZ3.
Nordstrand pickups have black, white and grey wire.
Question 1:
Which is hot and which is common?
Question 2:
Where does the grey pickup wire go?

Thanks.

Black is ground to the Audere
White is hot to the Audere
Gray is the pole ground and can go to a common ground

Nice, nice choice on the pickups. You'll love them. Make sure you report back to us how it all sounds when you get it wired up properly.
