2000 4x4. can't find a what the title states...anyone tell me where to get one?

The one made for the "Isuzu Rodeo and Honda Passport, and the Jeep J20 w/ Dana 60 axle" will do the trick. There's also one made for Chevy applications as I recall that works, but has 4 prongs instead of 2. Just cut 2 prongs off and it's good to go.
Here's some specs:
