Thanks for the tip Jamie.
I ran a wire from the blue/green wire from the switch through a VOM to the 
blue/green wire at the instrument panel and got conductivity, but I'll check 
the other possibilities too as soon as the weather warms up a bit.

if you have a TEST LIGHT or a 12v dc meter.. then you can try to follow 
whats follows..
