Re: 66 Jupiter; Tore up...from the floor up!
Ok, got it. Brought my battery, a light, my new switch (illuminated s.p.s.t.), a piece of cardboard (for the battery), wire, and plopped everything in the middle of the living room to watch a movie with the wife.
After a couple test runs, here is how they are wired. First run a ground from light to battery. Then run the other wire from light to copper leg (or bottom,#3) of the switch...then run a ground from center leg (silver, #2) to battery. Finally run power to top of switch leg (silver #1)...and viola...illumination and light both come on when switched.
Now I just have to wire the boat...
