My '68 has (as a grouping) the light switch, brake light, and a factory hole with a plastic plug in it where on other trucks I have seen the manual choke cable. My wiper switch is to the right of the ignition. The emergency flasher is above the light switch by about 3-4".
Better yet, hold the camera under the dash and take some pics of the actual switches and wires.
Might just be a spare light switch in case the other one goes bad - just reach up behind the dash, pull the connecter off and plug it onto the other one...:))]
