Wiper motor/switch help

[earl84]

This is what my wiper motor looks like. Can anyone confirm it is a single speed motor? It has 4 terminals, and I am not really sure which terminal is for what. The original wiring has been replaced, and I took pictures of the old and still have a pile of old wiring, but it was kind of funky and now I can't tell what goes where. The PO just had a toggle switch to run it, so it only ran in one speed. I am asking so that I can order the correct wiper switch as well as get this hooked back up. I just finished installing an AAW Wiring harness, and this is the last thing to do.

Also, can I order a two speed motor and a wiper switch with two speeds and a washer function? My truck has a washer bottle, but no pump as far as I know. Any help is greatly appreciated.
