Updated: See questions below after progress of working on the issue. Electrical questions. Thanks for your help! I picked up a new washer pump and was installing it. Instructions seem to make sense, but on the old pump, it was driven by something mechanical and this new pump is closed on the back where it attaches to the motor. Do the newer pumps not require the mechanical drive like the old? I posted a picture of the old back and you can see where it was mechanically driven. I posted a pic of the part label that I picked up. Before I go farther, this struck me as odd.
