Could they be the connectors for the cigarette lighter/ash tray lamp? Those are the only spade connectors I recall in that general area, at least as far as the 126 goes.
If the shift gate is similar to the 126 shift gate, the bulb socket should be located in the left front corner, kinda slides in at an upward angle.
