I saw the junction boxes and plan on using one, thanks!
I think I may have overheated the TV's brakes as it was starting to pull to the left on braking, which made me realize I had a problem. Luckily, by the time I got the splicing done (and yes, my hands were shaking too, it was very nerve racking), the brakes had time to cool and all seemed OK once I got on the road again. I am taking it in for state inspection and will have them give the brakes a good look at on all four wheels just to make sure I didn't warp something.
