Well im almost there .. I ended up going to a local audio place and they sold me a diagram. Its states for the 3.3 and 3.8 tach wire is gray/red, dark blue/tan and red/yellow at the PCM. My next question is . Where is the PCM on my 97? Also, If i probe with my multi at AC could i damage something if i hit the wrong wire. Thanks

Don't worry about going to the PCM. It is much easier to go to the coilpack instead.

I have four wires at the coil pack. they all show 30v ac and they do not register a tach signal on my remote start. I also tried the fuel injectors and it does the same...
