I just mounted underglow on my car?

I just installed underglow on my car a couple hours ago but I encountered a problem. They only give you about 2 feet of cord if that, so I have the connection running out the door to a bracket around 6-8 inches away from the exhaust. However, due to the lack of cord I have to run the cord under the exhaust pipe around 1 inch, I fear this isnt going to be enough but I cant think of another way to mount it so the cords dont melt, is there something fairly inexpensive I can wrap around it to have it resist the heat, or can u guys think of any other way to mount it where I wont have this problem.

Also, while at the hardware store I realized the connection is completely exposed to the elements, what can I put around it to protect it? Keep in mind to that like I said it is 6-8 inches away from the exhaust.
