I really don't like the Idea of "showing" electric trailer brake wire being grounded to the trailer axle. My axles move and is some what going to have a voltage drop when finding ground. My preferred method is to connect to the ground wire and keep the frame ground out of my schematics. By adding undetermined amount of resistance to the brakes you may end up with each wheel or at least each axle getting a different current flow and uneven braking. Thank you for having all this information quick and easy to find.
