Alternator Comparison

With an external wire from the "S" terminal to the B (output stud), the later PCM-controlled alternator can be installed in older cars if the correct connector & pinout are used. '98-02 4G cars will require the LG/R wire to be moved; older 3G cars will require the correct connector be spliced on.

ERROR - the caption of the far R wiring diagram should say:
Note Stator circuit is a battery-voltage feed to the PCM and police fuses.

ERROR - in the '98-02 alternator internal diagram, the trace from the right center diodes to the internal regulator should NOT be connected (black dot) to the capacitor trace.
