The CMSL (Center Mounted Stop Light, in 1986 parlance) gets its power directly from the filament monitor. The place to start is in the trunk, below the left hand brake light cluster. Pull back the interior material in the area between the cluster and where the power antenna is. To get best access, I usually pull up the rubber hatch trim, and have gone as far as removing some of the screws around the speaker that hold the material in place.
You didn't mention if the pictogram is lighting up - it should, if two or more of the four bulbs in the cluster aren't working. If the pictogram is lighting up, then the problem is in the wiring from the filament monitor to the bulbs; if the pictogram isn't lighting up, I'd suspect the filament monitor.
Tucked down in the corner is the filament monitor for all the rear lights and the connector to the CMSL cluster. Pin 5 (white wire) from the filament monitor is for the CMSL. From there it goes a very short distance to an 8 pin connector in the same area as the filament monitor and the power antenna. The white (power) wire from the filament monitor goes to pin 6 on the connector and up to the light (black wires, incidentally). The return from the light is also black, goes to pin 4, where it jumpers to pin 7 on the connector, and to ground.
Power is applied when the brake pedal is pressed. Look for power on pin 6 of the 8 pin connector. If you don't get power, trace back to the filament monitor. If you do get power, then the issue is the harness from the connector. The harness runs up the left side of the C-pillar (body side of the hatch) to the light.
Start with peeling back the material behind/beside the left turn rear turn signal assembly.
