Wiring... Plz help

You have to be careful mixing/ matching different year harnesses. There were minor changes. You simply have to sit down with the shop manual (MyMopar) and do a line-by-line continuity check Then there's "little" options like the key-in buzzer, map light, stuff like that, and in 74 or thereabouts, the dreaded seat belt interlock. And there's stuff "you never see". The incredibly stupid vacuum switch/ turn sig warning light setup "fuel miser" whatever it's called. And there was something called a "New York horn" Evidently NYC had a lower sound level tolerance on horns.
