My car is a 383 car and it has one, also the FSM clearly shows it in the engine wiring digram, it even says resistance wire.
Ok so some how it has one whats the big deal? It either was a factory blunder or some one added it. Either way so what. If it were me I would run without it. If it was a by the numbers and a full restoration of a Hemi or 440 six pack I would leave it. In the FSM i only looked under diagnosis and it made no mention that I found. In the wiring diagram I will bet it mentioned HP and hemi cars. Unless you followed that car its whole life from the day it was born you will never know.
