But not that simple -- for instance, the 3-wire configuration on a '77
alternator is not the same as the 3-wire configuration on a later alternator.
Splices are among the greatest gremlin areas in automotive wiring and should be
avoided if at all possible. If buying an alternator, you're better off if it's
terminals match the configuration on your wiring plug. All of this is IMHO, of
course and YMMV.
