Brake Light Switch Help

The third brake light on my '91 GTA stopped working. Checked the bulb and connections and everything looked right. Found that I wasn't getting any voltage to the light. From reading a few threads on here, looks to be the brake light switch. However, all the threads I could find regarding the brake light switch are for the early thirdgens, or as late as '89. All those have a different switch setup from my understanding. The '91 has two switches (unlike some of the earlier cars). I confirmed this by comparing it to my '92 T/A. My question is which switch is the one for the brake lights and which one is for the high-mount third brake light? Here's a pic of my switches:
