thanks again,
please feel free to offend. I am not an electrician, but do have experience with simple wiring.
I doubt it is stepped down, as the relay is just a small square plastic box, maybe 2"x2" by 1" deep. I can post a pic if helpful, but I think a bypass should work since the light is switched by the door button and therefore needs a constant hot.
here's a few pics, starter relay?
