Can someone tell me what the wiring diagram for the exterior trailer lights are.I hooked my new 1967 globetrotter up to my chev and The lights would not work.I had to find the break and signal lights on my tow vehicle and go directly to the lights at the back of my trailer and make the connection there.
What you experienced is not unusual with a Vintage Airstream or Argosy. It has only been in recent years that there has been a somewhat standardized wiring scheme for the trailer/tow vehicle connectors. During the years, Airstream has used a number of different wiring schemes. The scheme below is one that is found on the Airstream web site for 1966-1981 trailers:
1966-81 Airstream Bargman Plug Wiring
Typically the way that I have used the information is for the color coding of the wires (then as an additional check, I use a 12-volt garden tractor battery with alligator clips to verify the function of each wire) to match up to the function of the terminals in the modern Bargman Connector wiring scheme that can be found at the link below:

Good luck with your investigation!
