My parents just bought a 1995 Mitsubishi RVR. It's got a Starbo B-10 turbo timer. I haven't had any experience with turbocharged cars before, and only have a rough idea of what a turbo timer actually does (that's my first question - what exactly does it do?).
After I know what it does, I guess I need to know how to do it (try to ignore my complete cluelessness on this topic).
On the thing, this is written (incase you need to know):
STARBO
power metal oxide
silicon field effect
transistor switched
relay turbo timer
B-10
and:
MOS POWER FET SOLID STATE TURBO TIMER
[ ] [ ] [ ] [ ]
POWER 1 2 3
{ } { } { } { }
OFF |_ POWER ON _|
^ that's my attempt at a diagram of the other face of the thing.
[ ] = light
{ } = button
I'm not so clueless as to not know what the button between "POWER" and "OFF" does

The other 3 buttons though, between "POWER ON" and "1", "2" and "3", light up their respective lights. What do those numbers mean? What does turning the on do?
Thanks in advance for any help you can give me.
P.S. If anyone knows where to get any "Starbo" information, that'd also be appreciated - it's not often google comes up with next to nothing.
