Eletric problem with my '96 cherokee

Hi,
I have some electrical problems with my '96 cherokee 2.5 diesel. The problem is that the rev counter, and speedo meter falls down, and at the same time the fuel indicator showes that the tank is full, even tho it is almost empty. It happens only when I'm driving on rough surface.

Where can I find wiring diagram ?

Thanks

I have the same problem with my 1998 Cherokee Classic 4.0..the RPM and Speedometer gauges falls to 0 while I'm driving...also the Airbag indicator light comes on when this happens...I cant find a common short spot.
