Chrysler ran the current for the wiper motor and the washer pump through the multi-function switch and didn't use any relays or body computer to control their fucntion. Both are powered off fuse #2 (20 amp) in the underhood power distribution center that receives power when ignition switch is on. The service manual does show they both use different grounds, with the washer pump using G103 which should a the ground wire on the top of the upper radiator core support near the passenger side headlamp assembly.
