Need to replace both passenger doors. Need to know if the wires going into the car are pluged in or do I gonna have to chop'em and splice'em when replacing the doors?

 

there is a plug where the wiring harness goes through for all the wiring in the door,,,,,,if it is a bare door , you got to switch over thew wiring from the old door into the new door,, if a used door,, assuming same year and model, just plug it in

 

where is the plug. I trace the back door wires into the car floor spliced to another harness. The front door, not a clue. I am installing used doors.
