The speed sensor wire is not blue! It is Blue with Silver stripes. The Silver stripes are hard to see and the solid Blue wire is next to it in the factory harness. I bought the harness and Nav unit from Crutchfield. The tech support was awesome. The Blue wire voltage varied slightly but was not a negative pulse. The Blue with Silver stripe had a negative pulse and the voltage varied with my speed. That is how I found the correct wire.
