Tachometry Connections

Tach Sensor Cables: The tachometry connection is a very intricate part of the Gladiator and must always be connected. In most cases this can be simply done behind the dashboard at the tachometer display or just before the display. You must always refer to the engine’s owner’s manual or shop manual to locate the color codes and location of tachometry wiring. If you have any questions, please don’t hesitate to call our Tech Support at 1-866-559-0229

You will need to splice the Positive end (s) of the tach sensor lead (s) to the tach sensor wire from your motor. Negative end (s) connect to a clean ground. The other end will plug into the ECU at connection # 2. (You may possibly be able to pull and use a Black (-) wire from the wiring harness on some Outboards) See wiring diagram on page 7. The wire may be extended using shielded twisted pair wire.

For Single engines you will use the Blue (+) and the Black (-) wires. The Brown and White wire you will strip and twist together and terminate with a wire connector.

For Two engines you will use the Blue (+) and the Black (-) on the Port Engine Tach and the Brown (-) and White (+) on the Starboard engine. For three or more outboards; use the (outside) Port and Starboard engines.

Do not run tachometry wires near high current conductors or electrically noisy device.
