Do I need to remove the plactic cover in my trunk to unscrew the top nut of the shock absorber. Can you provide a diagram of this section so that I can see how both ends of the shock are connected.

Sorry, but we don't have that kind of information. If you are going to perform these types of repairs on your vehicle, then I suggest you go to alldatadiy.com and purchase an online subscription for their Honda Insight repair manual. It will provide the info you need for this repair and many others.
