it requires ECU power right?  does this power all three GP's in all 3 stages?

Yes it takes 5 v to light. I'm checking right now in the bentley if there are 2 signals. hang on a moment...okay in a  3 pin connector  there is one 12v for the control and then what seems to be two input  signal wires. I guess i should also mention there is a large 12v supply for the GP's and then 2 outputs-a 6.0 gauge to 2 GP's and one 2.5 gauge to the other. As far as the signals are concerned I'm just confirming what i had checked out my friends car when we were troubleshooting.
