The items we have are a cfd universal car power door lock actuator 12 volt motor a docooler car remote central lock locking keyless entry system with remote controllers.
Car door lock actuator wiring.
The remote has 10 wires coming from its harness.
A rod connects the actuator to the latch and another rod connects the latch to the knob that sticks up out of the top of the door.
In some cars the door lock actuator is positioned below the latch.
Both motor legs rest at ground at the relays.
I know enough about electrical wiring to efficiently burn the house to the ground.
Car door lock actuators are designed to lock and unlock a door without the effort of pulling on a cable and rod.
To lock or unlock the vehicle polarity is changed on one motor leg via a positive pulse from a switch alarm keyless entry etc.
