Bathroom vent/light wiring

[Uksay1]

I am replacing a bathroom vent/light. The new vent box has the wiring on the opposite side of where I need it to be. Is there a safe way to add (splice) extra wire to the wiring coming from the vent. The existing supply cable will not reach the new wiring. If so what size and will a junction box be needed?

Turn off your power and take the wires loose and go to Lowes or Home Depot and get you a plastic junction box with nails which you can install in your attic. Make this your splice and purchase a blank cover also.
