The Powerlet part in your link (PKT-042-36) is the correct part. I contacted Powerlet directly when I was planning to install this on my 2008, and they verified it. I installed the kit without a problem.
No doubt the Pashnit setup in a 36 inch length would work as well.
If you want to do the job "right", I would remove the gas tank and run the wiring along with the stock harness. It is a bit more work, but I wanted it to look as "factory" as possible.
If you ever have any questions, contact the Powerlet folks directly. They are a wealth of information and very helpful. I just had them make a custom-length cable for me, and they didn't even charge me any more than the "off the shelf" lengths... Recommended!
