    What I am reading indicated 5v comes FROM the ECM then through the MAF which drops that voltage to it's lowest point at idle and increases that voltage to the max of 5v at WOT. PLEASE CORRECT ME IF I AM WRONG. Sorry guys all I could find was stars to bring attention to the areas indicated that 5v should be coming from B12:
