Wire Location

Does anyone have any idea where these wires connect to?
1972 Plymouth Scamp, 225, Auto Trans, 7 1/4 rear end. The wires are DG & BRN, connectors are GRY. Both connectors are female, 1 is a dual connector other is a 3 connector. 3 connector has only 2 wires. I believe that this is in the passenger compartment under dash as that is where I had this combined with other wires form the harness. It is approximately 39” long.

BTW I have a FSM and several other wiring diagrams I have consulted that have been of no help
