I recently went to dealer to pick up a door lock actuator for the passenger side front door. It had only two electrical connections on it instead of three that is on my vehicle. The third electrical connector is for a plunger is what I was told and that he wasn't sure if it was needed. Does anyone actually know if it is needed or can I use the actuator with 2 electrical connections? Also what is the purpose of the plunger?
