I'm pretty sure my windshield wiper motor is going bad as on high my wipers are really slow. Was going to replace it and go to Advance Auto Parts to buy a new one and they have 2 different kinds. A 2 terminal and a 3 terminal.

What are the differences in the two?

Mine has a washer fluid pump in the same housing as the wiper motor but it's a separate part as I've already replaced it.

The wiring harness going into mine has four terminals on the end of it, but I think one goes to the washer pump.

But at Advance, in their pictures, both the 2 terminal and 3 terminal wiper motors show 3 metal connectors for the wire connection.

The 2 terminal has been discontinued and they can't even get it anymore, so I'm hoping I can use the 3 terminal, but they have to order it direct from the factory so I have to pay for it up front and want to make sure I'm ordering the right component.

Thanks!

EDIT:
Checking on some websites, it looks like some O'Reilly part stores in my area have the 2 terminal one, and another has the 3 terminal one. I'll probably just take mine off tomorrow and go to them and compare them side by side to see if I can figure out which one I need unless someone answers here tonight and knows for sure which one I need
