Bingo! Give Zekeman the cigar (or beer)!
There are two Solar Sensors in a dual optical device, right and left side in one physical device.
There is a 6-pin connector on the solar sensor, pin #1 is for the Drivers side (TSL), Pin# 2 is the Passenger side (TSR). These are outputs. 0.8 to 4.3 V A/C Amplifier.
Pin #3 is Ground and Pin # 6 is +V.
Attached is a PDF on how to test the Solar Sensor.
