I know its a little small, but those lines comming out of the door are the screws, hope it helps

- 2 on bottom
- 2 on outside edge
- 1 on inside edge
- 1 by speaker grill (under screw cover)
- 1 on inside of door handle assembly (under screw cover)
- 2 under the center portion of the door handle
- 1 in the sail panel

Yes, you should be able to use the factory wires, the only tricky thing might be drilling new holes to mount the speaker if it doesn't match up to factory locations.
