Wires hanging underneath the car

The car had been sitting for five years. I think a rodent may have chewed through some wires in middle area of car underneath. Now there are two different plastic pieces with several wires coming out of each one. One is more on the drivers side and is blue. The one more on passenger is grey looking I think. Middle area of car and they are hanging almost dragging to ground.? They look like the pieces may have possibly been connected by the wires? It is a GT model, convertible.
