So I take it I plug into the yellow wire? I was searching on sites and they all referred to the yellow wire as input. I guess they were talking about input to PCM.
Thanks for the help.

I installed the system and have a problem. I checked the voltage signal on the yellow wire and it seems odd. When the engine is off but key on it shows 5 volts. When I start the engine and let it idle it goes down to 4 volts. When I rev the engine the voltage drops down to 3.5? Should the voltage start lower and go up as more air passes? In the instructions for the Snow Performance kit there is an example. It shows setting the module to turn on at 2 volts @ 20% flow and then at 4 volts flow 100%? Do I have a problem here?
