Black
all wires should be color coded, that is black-hot, white-neutral, green-ground. national electrical code been in use since the dark ages. if the wires are not colored, take a continuity tester, test from the cord cap to each wire on the opposite end of the cord. the larger straight prong on the cord cap is the neutral, mark it with white tape, the smaller straight prong [parallel to the larger prong] is the hot, mark it black. the " u "shaped prong is the ground wire, the mosat important of the 3. mark it green. on the continuity tester, the light on the tester will light when you touch the correct prong to the correct wire
