If it is of course still a risk that the rabbit might escape again in the future which they have a nack of doing don't they.
I would cover the wires. There is a product you can get it is a bendy extendable tube which is designed to keep all the wires going to and from your tv or pc neat of tidy. But it would stop the rabbit being able to nibble them the rabbit would have to eat right through the tube to get to the wires. You would just have to make sure it is as flush both ends i.e. there is not much point if the wires are too long for the protective tube because the rabbit will just eat the bare/uncovered wires either end.
