Dakoris, relax take a deep breath the confusion comes from so many ways to that are fine to get the job done.

First although I am one who solders extensions since you are not comfortable with soldering then don,t do it just purchase extensions that will get the job done and avoid getting to much excess wire then for all connections that will be buried just make sure you choose any of the methods that has been presented here to make sure the plugs cannot get easily pulled apart.

You are in no real danger
