hey guys got one of the 5'' ? i beleive autometer tachometers with the shift light.. bought it off a friend a while back cheap no directions.. how do i hook it up..red green and white wire... ware do they go? ..
Red goes to 12V ignition, White to 12V lighting (for the tach's light) and greed goes to the negative coil wire for the tach signal. That's how I did it and it works fine.
