There's a lot of posts on actuators but they're old and didn't address my question, so here goes. Is there a difference between the power door lock actuators on a car with factory anti theft and one without? I'm not even sure that a Focus with power locks come without anti-theft. I've seen some actuators listed that mentioned ant-theft and others with same part# have no mention of this. Is the clue in the letters at the end ie BH, AG?
