This tach only works on 4, 6 or 8 cylinder gasoline engines.

but in fuel injection we can't find ignition coil. so where can I connect?

[@jimspring340]

You must have either an electronic ignition output signal or a connection to coil negative. This tach can only be used with factory standard ignition systems. If using MSD, Mallory, After market HEI or other non-factory ignition systems, you must use a tach signal condition. These are not recommended for racing as they are stepper motor tach and have about 3/10 of a second delay.

[@jimspring340]

No. It only works on 4, 6 or 8 cylinder engines.
