Ok i bought guages it says to hook it up to the ignition wire.....Where can i find that?
what gauges? unless you're talking about a tach and tach adapter, then you hook it up to any wire that is "hot" with 12v positive when you turn on the key. This would be any power wire going to any accessory (radio, etc) which powers up when you turn the key to the "ACC" or "ON" position.
