This guy said I need to cut it, strip it, and connect it? But where to cut, how to strip and connect?

From your question it would be advisable to get an electrician to come in and do the job.

Electric is dangerous if you don't know want you are doing and hurt or even kill u.

DO NOT TRY TO DO THIS YOURSELF.

creahands is right. You are asking this question as if we are standing there seeing what you are talking about.

If you describe everything in clear detail maybe we can help, but as it stands that is impossible.
