And it's even more than that. Everything got a ground wire in '69.
The dashboard controls moved around in '70 or '71 and changed
completely in '72. The turn signal wires were just a bundle of cables
up thru '70, but in '71 they got a connector at the bottom of the
steering column. The wiper motor and its wiring changed in '71. Then
in '72, the wiper switch got moved to a steering column stalk with a
new connector. '72 also saw the introduction of the seat belt warning
light and a changed buzzer connection. '73 got a (fairly worthless)
light to illuminate the heater levers. And there must be more that I
haven't remembered.
This is just one reason why replacement harnesses are never as good
as the originals, because they are never completely right, and often
they are wrong in very important ways.
