[Roadsters] early 67 roadster switches

[oliver]

there are four switches on these cars (light switch, fog light switch, 
windshield wiper switch, and heater switch)

the fog light switch appears to be a simple single throw, single pole 
switch.  no biggie to test.

the other ones, however, have multiple poles and multiple throws.

I have a very nice diagram (thank you slowboy) which helps.

I'd like to test the switches before I move on to testing the various items 
they go to.

can anyone tell me how to test any of them?  the diagram has the poles 
labeled, and where they go, but I'm at a loss as to where to connect power, 
etc, so I can use my multimeter to ascertain if the switches are working.

(I received the car in kit form, and have purchased additional switches over 
time, so I don't have the luxury of knowing for sure what was working)
