Wire location identification help

Lol. My bad. 1973 Plymouth duster factory slant 6 to 1976 400bb swap. I have gone through the fsm and didn't see anything that jumped out as the obvious location. I have the factory service 70'-76' and it actually says in there and Chilton that the '73 and up are so detailed that they didn't include it in there. I have another complete other 73 duster /6 car that the wiring is completely different on. So it was no good as a reference. My other son's 71 valiant got me through all the charging side, and he is so up to date on it he walkef up and identified 90% of them just by sight. The ones in question are 73 and up only wires.
