Dave, it isn't good enough to just check the wires visually. You need to test for continuity. Get yourself a digital volt meter. There is a switch in the female end of the sit belt buckle. Find the plug and disconnect it. Connect the meter and then connect the seat belt. if the switch is good it the meter should read zero ohms.

If the switch is good, then look at the wires.
