Connecting it will not make the wires live. I don't know what tools you have or what level is your ability. Joining wires if done properly should be safe but if not done properly can cause an exposed wire or partly exposed wire to come in contact with metal. I am saying it is not worth the risk stuffing around with trying to connect wires when the original part only costs about $30 in NZ.
