yeah you may have crossed a couple wires or screwed something up when putting it back together, hopefully the gauges arent broken
I recently had mine in for A/C service and they took out the radio etc. and when they put it back together nothing worked. They had blown fuses when they were messing around back there and once I replaced the fuses then eerything but the tach and MPG worked. So maybe you should check fuses.

ALso check to make sure you didn't cross the dimmer wire (if there is one) with the wrong wire. That's usually in concert with the dash lights and if it was crossed (or connected to say ground or 12v+) it could cause problems like you are seeing. But check fuses first.
