Wiring

The tacho input is quite flexible and can be connected to either...

• 5 or 12V digital tacho signals (ECU to instrument)
• Electronic ignition outputs (ECU to coil, including wasted spark systems and coil on plug systems)
• Fuel injector outputs (ECU to fuel injector)
• Low voltage side to coils as indicated below...

With recent model vehicles/bikes, it is becoming more common that a separate digital tacho signal is not routed to the instrument.  Instead they send it via the serial CAN bus as a message.  In which case, you just connect to an "ignition output".  Often this is easier to find than the digital tacho signal anyway.

An ignition output is one of the wires that goes from the ECU to an ignition coil.  You will have more than one of these ignition outputs, depending on the number of cylinders.  The ignition coil may be integrated into the plug that connects to the spark plug (known as coil-on-plug).  Find the coil and you'll see a couple of thin wires to it.  One of those wires will be a positive power supply, the other an ignition output.  You can either tap the tacho wire here, or back at the ECU.  It doesn't matter which ignition output from which cylinder you use... which ever is most convenient. You can also connect to fuel injector outputs.  If you need some extra wire to reach the ECU or coils, just ask us and we'll include an extra length for you.
