To my way of thinking, the "Pole Piece" is the star wheel that turns with the distributor shaft, with some relative motion due to the centrifugal advance (if equipped.) It has no wires.

The Pickup Coil has White and Green wires, that go to W and G terminals on the module.

There's three pickup coils for the usual V8 Coil-In-Cap HEIs with 4-pin modules. They're color-coded, and have different lengths of green and white lead wires. There's also two versions of magnetic polarity. They're NOT intended to be interchangeable, although some folks do.

This is a Pontiac-based web site, the Pontiac pickup coil has a white/clear, or no color coding, and has the longest lead wires, along with backwards magnetic polarity from the Yellow-coded pickup coil. (But same magnetic polarity as the Black/Blue pickup coil.) It would be used with the ignition coil-in-cap having red and white wires.
