Oh, frack! That's even easier! Yes, they are currently wired into my
alarm system, which switches grounds to actuate them. So yeah, I can
interface with that much easier. Duh...

I was approaching this from an angle that didn't include the alarm
system because I was looking primarily at the trunk release which
ISN'T on that system. In the process I forgot that the launchers are
there, and that the trunk release will also be there when I finish
wiring it up.

This method won't produce an interlock for the alarm system's outputs
to those actuators but that's OK, as I simply can't see that ever
being an issue.

Thanks for such an obvious solution. I should have found that path, I
guess I was too caught up in various other methods and ideas to see
it. :)
