took it apart, typical reverse polarity motor gear.
Uses the green wires to move the arm. Polarity reversal moves motor other way. Motor shuts down when lever arm moves to lock or unlock, then wire polarity has to be reversed to move it back.
Black and brown look like wires that could tell the car the door is locked or unlocked. Those are unused AFAIK, I have no indicator light.
advantage of the newer design is the metal move arm, the earlier 1996 one has a plastic arm and that arm broke in the crash.
I have no idea what stopped my original actuator from quitting, but I can rig this one into the wires since I know how it works. Hard to think the existing vehicle wires broke, that seems doubtful. All the other door locks work ok.
