So the vibrator must have been used to change the DC to AC, then routed through the transformer?

You're splitting hairs, call it what you want real world it's AC noise riding on DC. A 10uf cap fixes it. PCM is happy and relays in the headlight circuit won't chatter Trying to help the layman here not the scientist
