Q: How do you install it？

It may be possible to mount it on top of the vinyl siding and then caulk around the edge.

Q: Do i have to remove the old electrical box to install this? old one fell off due weight of the new light

Yes, you will need to remove your old box. Make sure to shut off the power to that fixture, remove the light fixture, remove the box, slide the Octagon Siding Mounting Kit over the wiring (important: make sure the power to that circuit is OFF), attach it to the siding and then reinstalled your light fixture. If you’re not comfortable then call an electrician for the job. Good luck!
