Maiden Voyage, Brake Wiring Harness Problems

Seems like cleaning and reattaching the ground and putting in a longer umbilical cord are the winners, which is what I was hoping to avoid. We're at the hottest time in Arizona and the last thing I want to be doing is laying on my back on a blacktop under a trailer attaching a cable that my life depends on.

Gotta love the RVing lifestyle. :D

Thanks everyone for the quick responses, even if they confirmed my worst-case scenario.
