Not sure either but the instructions call it a confirmation check or some such. I don't think it's a calibration. Maybe something will get fried if you made that connection incorrectly and proceeded with the rest of the connections without checking? I figured they had a reason and I wasn't going to second guess them and end up with a fried unit or worse something on my bike fried, so I just followed the instructions like a good boy.I still don't understand why you have to connect 5 wires then turn it on to flash the indicators and then connect the remaining 3 wires! Seems an odd calibration procedure, but I did it and everything works very well.
