Re: sensor ID
Probably right. Simple to check. Find the wire diagram and get an multi meter, set it to ohm and wire test it.

Re: sensor ID
qq rather than start another thread ..... lq4/4l60e
VSS Doesnt the PCM get this info from the sensor for idle/gear details etc. How do you use the VSS for gauges then if its going to the PCM ? Splice into those two wires (Green 20 + 21 for VSS low/VSS high) That way both the PCM and the gauge cluster get same voltage signal ?

Re: sensor ID
No, you dont want to ever tap into the VSS wires, even though some gauge companies say to do so, it will mess up the signal going to the PCM and can cause issues. There is a dedicated speedometer output from the PCM that you can use for the speedo.
