No Tach or speedometer.
Just when I was thinking about selling the truck this happens.
Starts great, runs great just no tach or speedometer.
Where do I start looking? I just put on a new track bar ( 3rd one, lifetime warranty), did some work on the power steering hose and now this.
Any ideas?

Tach is controlled by the CPS. Speedometer is controlled by the tone ring sensor on the rear differential. That said, I believe the auto's have a second speed sensor in the output housing, but not completely positive about that.
