You are going to need right and left stock window regulators, any brackets, door knobs, mounting screws and bolts etc. You should research what the stock set up looks like installed and how it works. Most electric kits are pretty simple attaching to the bottom of the window and the inside of the door after removing all the manual crank stuff. You may be able to install the electrics better, tune them up and be quite happy. Try to figure out who made your kit, see if they have a trouble shooting page/help and make them work right. There are a lot of hacks out there that just make headaches for the rest of us! I have and still am considering doing electric windows, I is sooooo convenient to be able to roll down the passenger window (AND UP!) from behind the wheel.
