got the car hauler trailer fixed up.....oh it was fun!... New 7 way plug & harness with junction box and new break-away kit with charger and two new grounds and some other misc wiring. A junction box is the only way to go on these things...makes things cleaner and easier to fix if problems later. Wiring was not complex...but it did not help things where the mfg changed color on the 7 pin from what the truck calls out (guy who made the trailer, I guess that might be common...but when the plug says use green and the use whatever color is laying around..) ... well I now have some additional custom wiring..but I did it, so I know the secret squirrel stuff this time
I can only blame myself if I crash and burn now 
On to the wiring for the seats tomorrow and other msic stuff...that I don't have to do, but if I'm on a roll I might as well make some progress.
