Okay, here's the story. I got an 89 Mj automatic,column shift,4x4. It had the idiot lights. Like everyone else I wanted the needles and tach. Did the switch (Got and installed all sending units). The gas gauge, battery gauge, oil gauge, and temp gauge work. The speedometer worked for a while then stopped. The tach does not work.
What could the problem be? *Speedometer is connected.*
What is a solution? Any and all help is appreciated.
