Re: [A/S] Early 60s trailer wiring

Eric,
  Wire the connector on the trailer to match the modern standards, don't 
change your vehicle.

Although you can and should pay attention to the colors on the trailer 
pigtail, the best method is to actually test the function of the wires 
on the pigtail to confirm things. Using a battery and an inline fuse, 
you can easily check out the functions, make a diagram, and wire the 
connector accordingly.

When replacing a bad connector, I've often found that the pigtail cord 
is also in need of replacement. Sooo... I'll prewire a length of the 
special "trailer" 7-conductor cable to the new connector, then route it 
to the junction area and connect it to the trailer wiring. The junction 
area is often found under the trailer, perhaps near the step. There will 
be a cover that's attached to the belly skin with pop rivets; proceed 
accordingly.
