Wires colors didn't change much at all in the early years. A 69's water temp switch wire is a 20 ga dark green. If you find that color in your harness, ground it through a test light to see if the dash light illuminates. The reason for using a test light is if, for some reason, the wire is hot and not just 12 volts through the dash bulb, it won't cause a short.
