Any ideas on what I might have miswired?
I agree with Brett - - this is what happened when I just plugged the trailer into my tow vehicle just after purchasing the Overlander. At that time (1995), I didn't have any wiring information available so had to use a 12-volt battery and alligator clips to determine the functions of each wire. On the Airstream site, there is a diagram for 1964-1965 coaches that corresponds to the wire color coding that I found in my '64 Overlander and will very likely correspond to that in your coach - - you can find this document at:
1964-1965 Airstream Bargman Plug Wiring Information
The key to using the diagram is to match the function of the Airstream's wire to the appropriate terminal on the plug without getting overly concerned about whether the color matches that used in modern applications.
Good luck with your wiring project!
