Denso Alternator Installation

You are correct that the blue wire is the sense wire and the green wire is the ignition,that is how the plug is wired when you buy it.It the post I mention to remove the wires that come with the plug.There is no need to splice wires to that connector.Look at picture number Three, all I did was cut the original blue field connector,installed connector that fits the denso plug.Use the schematic as a point of reference only .The color of the wire does not matter as long as it is wired correctly.I hope this helps you.
