Airstream's wiring code back then had three wire colors different
from the current code. This difference can be found on 1966-81, except
those built to Canadian spec's in 1969.
The differences are:
Yellow is the brake output rather than backup
Black is backup lights rather than charge line
Blue is the charge line rather than brake output
The others remain the same as today's standard, which is:
Red is left turn and stop
Brown is right turn and stop
Green is marker lights
White is ground.
