The trailer that I bought, has electric brakes and electric lights.

The lights worked intermittently, such as worked only once or twice.

The electric plug is a two piece job, with wires held by screws, some
wires fell out. Not good enough.

I bought a replacement molded one piece plug with 8 foot tail, and
will use it. What I want is to do a good job rewiring the trailer. I
believe that the trailer body is used as negative ground, which is not
so great when there is corrosion. So I want to be sure that I follow
"best practices" and to know what they are.

Any suggestions?

i doubt there are firm rules. For me number one is put everything in
conduit, number two is no daisy chaining (run a separate wire to each
light and each brake from your central junction box at the tongue)I
also silicon seal all the crimp connections by putting the silicone in
before crimping and then wiping smooth.

I did this on the trailer I bought 22 years ago and sold last year.
Never had a failure the whole time.
