    It depends, One is positive to drive a speed, it may have 2 speeds and it even may have park. More info needed

    Post a picture of the unit, maybe a model number and make too. A two speed motor will usually have 3 wires. The - wire goes to the negative bus on your distribution panel, the two positive go to a 2P2T switch. Most of these motors are self parking, but some will have an extra wire for park.

    There are 2 circuits possible.
    With B+ and B- connected, the motor runs continuously. With B+ connected to "i" instead of + the motor completes only one swipe (type A). Other brands have B- connected to "i" for single swipe operation (type B).
    To find out which one you have, momentarily power the + and - to make the motor leave its end position. Then measure the resistance between - and "i". If the reading is zero, your wiper is type B.
