    Ok some of my guys are allowed to take their trucks home. One of my employees took his truck home and towed his buddies trailer, which had the same 7 wire plug we use, however it was wired wrong. I guess the ground pin, was connected to the charge pin. There for none of the wiring worked.

    However it blew 2 fueses, big suprise huh. They also found 2 rellays nice a warm, those were probably fried too. 2 new rellays will be installed tommorrow. Currently the all the pins work, except the back up lights, and charge pin, the two rellays that were warm. Hopefully the 2 relays will fix the problem.

    The warning from this post is, make sure if you are towing a trailer other than yours, even if it has the same plug, check to make sure it uses the same standard.

    Total cost, 10 dollars for the rellays and maybe a dollar for the fuses. Better than a burned up truck.
