There are a few KEY parts in the write-up. One, the solid pink wires are 12v when the key is on. Every 1999 and up this is true for. Two, use the wire taps as they suggest. I bought a package from Radio Shack for about $2 and they work awesome.
The way I did mine was pull the drivers side A-pillar off and cut a hole in the defrost tube. I ran the wire through the hole in the tube and down the door jam in between the fuse box cover and the door to body seal. From there, I went under the kick panel, under the center console, then behind the panel on the passenger side they tell you to remove to access the grommet. Up through the grommet went all three wires. For the power I used pin #19 on the blue harness. The Tach signal obviously the #10 pin on the red harness. And the ground wire went under the PCM plastic holder and was fastened down by the bolt you removed to get the holder out to start with.
Hope this helps you out!
