sovereign (dual axel) 12gauge was original, and, I think, 12 guage is also installed on the MoHo to the tag axle brakes (electric), but it may be 14 gauge.
For the price difference, I would not even think about running anything smaller than 12 gauge.
There was another thread here recently that discussed (debated?) the pros and cons of fuses in the various circuits involved in the brake system.
The factory set up on the '78 was a single 50 amp fuse shared circuit to the electric jack and break-away switch....remember, when activated, the emergency (break-away) switch is going to throw a full 12 volts to the brake magnets - this will draw a lot of current (and create a lot of heat SOMEWHERE - either in the lines or the magnets themselves). The ¨normal¨ activation of the brake controller would probably present around 6 volts to the brake magnets. With a 50 amp fuse protecting the battery, I would think that a brake magnet would open circuit prior to the 50 amp fuse. Battery life would be VERY short should the break-away switch be accidently closed.
Also, on the ´78
Sovereign, the wires are partially in the belly pan and partially in the frame - I would think it would be a personal preference as to how you would run them.....half inch metal electrical conduit on the exterior of the belly pan would hide and protect the wires.
