The pump relay switches the hot side of the pump motor. The ground side is always connected to chassis ground.
The washer motor relay is in the underhood Distribution Box. The relay layout in that box is different from 4-cylinder to V6 so be sure that you are using the correct diagram and looking in the right place for your 4.0L. Also, are you sure that you pulled ALL of the relays? A few are the common Bosch-pattern automotive relay (square) and others are about half that size and rectangular. The washer relay is one of the smaller ones.
Looking at the schematic, it's hard to see how the pump motor can run without the relay in place. The only way I can see is if another hot wire is incorrectly crossed to the pump hot somewhere in the harness. If so, that would be a very unusual problem.
