Wiring?

So I've been going through the wiring on my 79 and I'm trying to identify 3 wires under the glove box. It's a 3 wire connector with a blue w/red strip wire, black w/yellow stripe wire, and red with black stripe. The wiring diagrams that I've found haven't been very helpful. Does anyone know what these are?

Blower motor Blk-Yel to resistor, then 3 wires, Blk-Yel, Blu-Red, Red-Blk. Pay no mind to the red "to radio" circle in the 2nd diagram.
