I got it fixed. Had to install a "pull up" resistor on the signal line for the speedo to work.

Apparently when I pulled the factory dash I also pulled the pull up resistor. IT works great now. I still need to tilt all the gauges back so I can see them as the factory dash will not allow that. I am going to build a aluminum dash and reinstall the gauges. Name: IMG_3040.jpg

It might be hard to see in the photo but the gauges little toward the driver and make it hard to see them.
