HARNESS PIGTAIL, ALTERNATOR, AD STYLE
This alternator plug-pigtail incorporates a Weather Pack style seal and an in-line resistor that allows, but does not require, a charge light in this exciter circuit. The exciter wire is blacked out as it leaves the alternator plug, so that little bit of wire going into your flex loom isn't as noticeable.
