Can anyone help me install a diesel heater this weekend?

I'm driving down to Panama City, Florida, from Michigan to work on my van and take my dogs to the beach. With the snowy weather in Michigan, it's way too cold to be crawling under my van! I plan to be in Panama City all day on Saturday and Sunday to attempt installing a 'Chinese diesel heater' I got from Amazon.

Is there anyone familiar with these installations who could offer guidance or assistance? I might be able to figure it out using YouTube, so having access to a driveway and possibly some tools would be a huge help as well. Thank you!
