rev counter installation easy?

[modmonster]

hi

my corsa doesn't have a rev counter. is it easy or useful to have one? or is a vacuum gauge way more useful?

if you get a tiny tac, they take about 3 minutes to install and cost about $45, I have one installed under my hood just for tuning the engine.

Usually just 4 wires, power, ground, light, and tach pickup. The tach hookup goes to negative lead of coil.

tiny tac has two wires, one wraps around a spark plug wire, the other is a ground wire, the most difficult part is choosing where to mount it.
