I have a '93 Ranger with the 2.3L. I took the dash part of the way out to replace the heater core. Now that it is all put back together my gauges do not work. The only operational thing is the speedometer. Has anyone else came across this problem and if so how do I fix it.

 

On the back of the instrument cluster (which faces the front of the truck) are two fat sire harness connectors. It is possible they became dislodged when you move the dash.
