2005 Buick Century Electrical Problem

I replaced the water pump on my 05 Buick century. I did sit my mechanic set on the right side of the engine compartment. (possibly on top of some wires). Now my car starts when i turn key to on (not to start). And my instrument cluster won't come on nor my radio, the instrument cluster lights work. and the turn signals work along with the service engine light. I checked all the fuses that seemed related to it with no blown fuses found. Is there a wire under the hood near the top that would cause this?
