Wiper motor wiring

[J-440]

  Ok, got a 3 speed wiper motor and the dash switch has 7 terminals.  I've got 4 wires coming from the wiper motor.  I've pretty much got it figured out but I was wondering do I need to ground the switch?  I've read the wiring diagram but don't see a terminal for the ground.  Thanks.

The switch gets it's ground through the dash.

 Thanks guys, I completely forgot about the MyMopar website and their free wiring schematics.  Thanks again.

 Now this is interesting.  The 7 terminals on the back of the wiper switch, from the 3 speed wiper motor the brown wire looks like it is solderd to the switch.  It's hi-lighted as a "circle" on the MyMopar website diagram.  I have all the other wires connected correctly except for the brown wire. 
  Also, do you have to have the washer pump 2 terminal switch connected to the wiper switch to make everything work correctly?  I have no washer reservoir and have left the pump button non-functional.  Thanks one more time.
