Has the Marauder a positive or negative polarity at the door lock?
Who knows that?

All modern cars are negative ground... :rolleyes:

OP wants to know if the door lock actuator is triggered by grounding the actuator or apply power to the actuator.

This is a quote from the Ford Electrical Shop Manual:

"(The switch) Controls a bi-directional motor by supplying a momentary ground or power to either side of the motor, depending on the position of the switch".
