John, your issue is that you do not have an understanding of electricity...
Voltage is not current (amps).
The 5vdc is a reference, and is changed as the ECU activates the vent solenoid..
That current would be in Mamps...
Your circuit would be system power (12vdc), not the reference, test loaded with a 4amp load...
