I am installing a hydrogen system on my 2002 Sedona EX and I am having one heck of a time finding the MAP (Manifold Absolute Pressure) Sensor wire that goes to the ECU. there are three wires: one is the power wire another is the ground and the last is the wire that goes to the ECU. I know where the MAP sensor is but I am having a hard time deciding which is the correct wire. If anyine knows the color of the wire please let me know. I do not want to tap into the ground so I am looking for help.

Thanks.
