I found said wire, and traced it all the way to the instrument cluster. It outputs around 20v AC. The signal I need has to be between 1-6v AC. Any ideas?

EDIT: It also says I can use Oil Pressure or High-Voltage Sensing, however due to COP's I cannot use the High-Voltage Sensing.
EDIT: The yellow wire thats supposed to be tach that I tested goes down in voltage when I rev.
