This pic is of the 12VDC common ground wire that wrapped around the rear of the trailer.. It was easier to just replace it with new wire than have to replace every one of the Scotchloks with a properly crimped butt connector with shrink wrap..
After towing the trailer over to the storage unit, I could already tell the difference in braking performance from removing the excess wire from that circuit.. I had to drop the gain on my Prodigy from 9.5 down to 7.0 to keep the brakes from being so grabby.. The brakes now work as well as the electric brakes on my other trailers, it can actually lock the wheels on dry pavement now.. The trailer also seems to have better road manners and ride quality traveling with a full water tank after relocating the tank to the centerline of the trailer.. Traveling over the same roads/same speeds that before would have pitched all the dinette cushions on the floor and rearranged the cabinet contents, this trip resulted in no cushions being thrown to the floor and the cabinet contents were not so jumbled as before.. The trailer also seemed to be less twitchy after moving the tank and it's nearly 200 pound filled weight out of the far rear corner..
