| Terminals changed over the years, so it may be best to look for part numbers, and google them to establish a year. Then you can check the wiring diagrams in the technical section, and know how to test them. One speed, two speed, self-park, etc are some of the variables. And watch how they ground carefully. |

Be very careful testing the ones still attached to a regulator, those things would love nothing more than to separate you from a digit or two.

Yes, it depends on the year.
Some are very simple as they are only on/off and often ground via the body (mounting bolt).
Later ones are more complicated as they have more connections and may self-park as well.
This means they have a connection that has constant power so that when you turn it "off" it still has to power to finish the parking motion.
There are a bunch of existing threads that may or ma not help if you start digging through them:

Yes... remember that they have arms and gearing that magnifys the force coming out of the motor. It can definitely mess you up if you get a finger caught in there.
