Need help To convert to power windows

Hey Guy I have a 94 Honda Accord DX. Now I will like to give this car all power option to the doors. I was told to get the door from an 94 accord ex my question is do I only need the harness that is in the door or do I need to get the complete harness out from under the dash and if so where dose that harness end please guys help me.



Thank you all
