There is a disconnect in their i2c designs. The normal i2c connection has 4 pins (ground, power, scl, sda) and most of the plugs have 4 pins.
But the ambient light sensor wants to pass a 5th pin (called nInt, which presumably is a pin that goes high when the state changes so that you can attach an interrupt so that you know when their is new data).
They put the nInt pin between ground and sda pins, which means you can't intermix 4 pin and 5 pin i2c connections.
