Dome light switch

[jsdoyle]

I was wondering if when you turn the headlight switch to turn on the dome light if the switch completes the ground or supplies power to the dome?

I moved my dome light to door jam switches but got to thinking if it's the ground on the switch I could wire that in to then also have the interior lights on the doors and the switch.

I can test it... but maybe someone knows off the top of their head.

Thanks,

Scott
