Ideal for vehicles with late model engine swaps and applications where conventional tachometer signals are not available.
- Compatible with 1-12 cylinder engines
- Measures 1.5” x 3.5” x 2”
- Environmentally sealed and vibration resistant for underhood mounting
- Wire lengths: Gray (signal out) 52", Black (ground) 24", Red & Red/Grn (Ign. Power in and out) 24"
Rated 5 out of 5 by 81svtcoupe from Easy to install I purchased this to get the Chrono Tach working in my 1981 Ford Mustang 03 Cobra swap (4.6L Supercharged) project. The instructions was super easy to follow, install was very simple and I was able to hide it in my glove box for a simple easy installation. A++++ for another fantastic Autometer product.

Would part 9117 be needed a a 4 stroke, 2 cylinder ATV? The ATV has a coil for each spark plug. Or would it be the same as Deecee 's question? (1 pulse out of the box.)
Unfortunately this will not work for you. For further assistance please give us a call at 866-248-6356.

Will the 9117 Tach Adapter work with my 2006 Subaru Impreza Outback Sport, EJ253, manual. I have a 12v ignition power wire that comes from the main relay to the coil pack that looks like the wire that needs to be cut.
This will work with your Impreza. The 12 volt power to your coil pack must be diverted through the 9117.

Will this work on a 1992 Honda Beat? 3 cylinder 660cc motor (E07A)
This is not needed for that motor. Unfortunately with very limited data on that vehicle I wouldn't have any information on where to properly get a signal from that vehicle.

Hi, i have a Rotary 13B engine and i cant get my RPM digital gauge ( AU3387 ) to function accurately. It is a twin coil electronic system. Is a tacho adapter needed ( 9117 )? Can you please confirm the pulse cycle for a Rotary engine. Thanks, Dave
You will need an Auto Meter 9117 tachometer adapter. Locate the black wire with white stripe that is common to all 4 coils. Trace this wire back and cut this wire in a position that all 4 coils are now dead. Verify which cut half of the blk/wht still has power and connect that to the solid red of the adapter. Connect the other cut half to the red/grn of the adapter. Ground the black adapter wire and the gray adapter wire will now produce a good 4 cylinder/2ppr signal.

Will this Tach Adapter work on a 1990 Nissan 300zx TT. I have a fully built motor and I am running an AEM version (series) 2 Stand alone ECU. Currently I am not getting a signal to the RPM Gauge.
That vehicle won't need our tach adapter. The signal can be pulled directly behind the dash off the harness by the gauge cluster.
