It's a gauge for tasting/measuring the condition of the vehicle when it is on.

Does it have an onboard computer or something??

I just don't understand why something as simple as a tach needs to be always on. The only reason I can think of is if the actual working of the tach is digital and so it doesn't lose it's "memory" in the off state. I can't see the reason for one of those compared to a mechanically driven one though.

Do you just want the dummy (shift) light so it looks cooler?? lol

i think you misunderstood something... or i wrote something weird... i dont want it always on.. i just want the tach on when i have the engine on. and dummy shift light? since when did i have a shift light? i bought the cheapest tach i could find lol. i just need it for the winter to notice my tires slipping. (actually dead leaves are quite slippery too) i need to find a wire that is on when the engine is running but off when its dead. i tried the "gauge" fuse and it didnt work, as other things started to not turn on...
