Door Speaker Wiring in '88 Vert...?

So I picked up an '88 Vert 4-banger awhile back for a grocery-getter... and it had no sound coming from the door speaker area. I took the door panel off today to find no speaker, and a partially covered speaker hole. I don't think a speaker was ever installed there and upon inspection of the wiring, there look like there were two small wire ends that were cut off. One was blue and the other was green I think, both of them had stripes too. They stuck out of the harness that ran to the power door lock buttons and actuator. I spliced speakers into the wires and got no sound...

Anyone with Verts run into the same thing? Will I need to run my own wires?
