Mystery to me wiring harness

[dodgemahal]

I'm restoring a 1973 4 door Dart Custom. There is a 2-wire harness with a connector at the end that's under the carpet and just to the right and adjacent to the transmission hump. What does this connect to?

Butt detector in the seat for the seat belt warning?

I'll get some pictures tomorrow. Im pretty sure there's no connector on the seat. There's wiring going to the seatbelts that are attached along the door openings. They trigger the dash light.
