Each of the four connectors is a different color, and a specific
connector is also available in different colors - colors such as red,
yellow, white, blue, green, gray.  The reason for all the colors is that
each connector is keyed different - and the weatherproofing requires
connector shells that exactly match the harness usage.  Unused positions
are molded shut, it is hard to add a pin where there wasn't one.  Thus,
if your '727 use doesn't exactly match a factory configuration, you may
have trouble hooking up some signals.  (With the '730 style connectors,
it is possible to pull the pins out of the shells and move them around
as needed.)

As for a 727/730 4 cyl. MEMCAL, look for 1987 (only!) J-cars with the
2.0 "1" engine, or for a W-body with the 2.5 L4.
