Help with 3 wires behind my dash (87 model)

I have three wires behind my dash with no apparent place to connect them. This is an 87 model wiring harness and the three wired fall out of the harness near the radio and heater control area. Their colors are black, yellow, and grey.



I'm thinking factory radio connections. Am I on the right track ?

If it is for the radio, it'd be your illumination, +12 switched and ground wires.

I appreciate the quick responses fellas. I'm a no radio kind of guy so I'll go ahead and cut them short and heatshrink them.
