Here's a view of the passenger-side glovebox cavity. The two black rectangular boxes with the wiring harnesses attached are relays for the system; one is the power relay (with the heavy red wire) and the other is the high blower relay. Note the third white ground wire connected to the center portion of the dash crossmember. The A/C thermostat switch is located just below the crossmember, behind the VIN plate, within convenient reach. Though it looks (and is) pretty busy in here, the glovebox still mounts without a problem.
