Got the Speedometer working nice and smooth now except it is off a little??? I set the DIP Switches to the same setting as the Old ones were. Need to find out which ones to switch to Up the Speed some on the back of the Speedometer. I drove 25 miles but only registered 18 miles so I know I am going faster then it shows! Did not want to just start flipping them (Off/On) to see if I could get it right.
