Is it really that intricate? Obviously I haven't really hashed it out, and I'm just a hobby/amateur electrically, but I wasn't thinking of any "smarts" in the system.
I was pretty much just thinking of tapping into the dome light circuit for the trigger side of the relay, and having the switch side just feed an always-hot supply into the existing window circuit after its relay. There would be juice getting to the windows with the light off and key on, with the key off and light on, and of course when both the key and light are on. The last scenario does give me pause though, not sure if it's really wise to have 2 independent hots going to the same device that might actually see each other. If I actually took some time to think about it, I bet I'd realize I'm missing a big pitfall, but that was what I was going to explore.
