after market speedometer install question

Which wire would I connect this to? I have a 4l80 with the vss wires going to pins 22 and 23 as per the swap thread on this site

My gauge instructions state to connect the wire to the output of my speedometer sensor. Which wire would that be? Thanks

Neither, hook it to the speedometer output from the PCM.

Just in case anyone finds this thread while searching

If you're still using your ecm, you'll connect the speedometer wire to the high side of your VSS. PIN 21 on the red or green connector
