On modern trailers it makes no difference so unless you hear something different from an owner of a '49, I would think the same should apply in that case.

The brake magnets don't care which direction the power comes from ,as long as it is there.

When electricity is applied to Electromagnets the behaviors are similar to natural magnets. In electric brakes, controlled magnetism is needed... this is the electromagnet’s special behavior utilized in the braking process.

So, no it isn’t, generally an electric current polarity issue.

It is good to mention here that sending power to a device also requires proper grounding. Do not skimp. The primary brake feed wire and ground must size match on both TV and AS.

I would oversize. ANCOR Wire Products for all components. West Marine, or Waytek. Heat-shrink terminations.
