stock to autometer wiring

Just to update this thread.
If you run a mechanical Auto meter speedometer, buy the cable from NAPA for 65 Dart it is the proper 63" length and fits!!!! $20.00

Mods need to make this a sticky, I searched over 4 hrs on the net unitl I found this post.

I am running an electronic speedometer. They gave me a device that screws on where the speedo cable goes and has electrical connections for wires to run to the speedo. I understand that I will also have to calibrate the speedo once it is powered on. That's why my speedo is stuck at 40MPH fresh out of the box. AutoMeter tech set me straight on that.....
