Hi. I've currently got a device wired up to a toggle switch in my '98
Mustang. Right now, I've got it wired right to the battery, so if I
forget to turn the switch off, naturally it drains the battery
(something I don't want to do). I was wondering: does anyone make a
switch (always-on or toggle) that will only send power when it
receives a signal from the ignition. I'd rather it be setup this way,
but I'm currently unable to find a suitable switch. Any help would be
greatly appreciated.

Thanks.
