EMG Quick Connect Pickups: 1 Conductor?

I'm having a little trouble determining how many conductors the EMG pickups use with the quick connect pickups. Are they all just 1 conductor?

If you look at the schematic for the EMG 81 humbucker, and you look at the "From Pickup" connector, it looks like there are two different connector wires. The red wire just looks like it's a wire for the battery and the other wire looks like it has 2 separate wires inside. I looks like the 2nd wire is the conductor (white) and a ground (black). So it looks like there is really just the 1 conductor for each pickup.

Can someone please confirm this?
