1972 Dodge Dart Swinger Odd BUZZZZZZZZING Noise & Seat wires?

My car had the seat belt interlock module in it, so it would be wired differently than a 1972 would be....... I think the factory manual might have that wiring diagram in it..... Besides, I completely rewired the dash ( removed the fasten seat belt\ interlock wiring)..... Wished I could help.....
