Looking at a diagram, you might be able to get it behind the instrument cluster. Check for a red/yellow wire located at pin 12 in the big 46 pin plug.

AC voltage should increase with speed.

If it does not increase with speed, try your meter on DC voltage. Depending on your meter type it will show up on one of the 2.
