Dimarzio PJ148 pickup

I'm pretty sure I bought this from the classifieds, and think it was described as an Ultra Jazz. I noticed another Ultra Jazz in the classifieds today and saw that it had 4 wires. This one only has green, red, and gray. If I google PJ148 I can't really find any info on it. Whats the story with this pickup?

I'm curious about this as well, but what I stumbled upon was the PJ147 on ebay.

There's no "PJ" designation on Dimarzio's site for bass pickups, so I'm baffled.

But they do look identical to Ultra Jazz pickups, from what I can tell. I have one in my Squier and it's also got that wiring.
