This fully potted, weatherproof module can be wired into the power supply of a coil per cylinder ignition system, where it senses current and creates a conventional 12V square wave signal output which can be utilized by AutoMeter tachometers and many aftermarket RPM activated devices. Ideal for vehicles with late model engine swaps and applications where conventional tachometer signals are not available.

Hi, I am installing a 2017 coyote into a 1964 falcon and want a tacho. can i use the adapter to generate the signal for the gauge?

Asked by: chopper
Hi Chopper, thank you for the question. The Tach Adapter would be required for and would drive an AutoMeter tachometer. However, we could offer no recommendation or guarantees on driving your original tachometer.

I mounted your NV 5" pedestal tach on my drag bike. The motor is a 2002 Honda flat six from a GL-1800 gold wing with three coils. Do I need to use the tach adapter model 9117?

Asked by: Deecee
Hi Deecee, thank you for contacting us. No, the 9117 should not be needed. It will likely be a single pulse per revolution at one of the coils. All of our Pro-Cycle motorcycle tachometers are capable of 1 pulse out of the box.

Hi I have a 1995 mustang with a 3.8 which had a dis ignition, I swapped in a 302 with a duraspark ignition. Is this 9117 adapter what I need to make the stock tach work.

Asked by: dusty
Hi Dusty, thank you for the question. No, you should not need a 9117. The Tach Adapter was not required until the 1999 models. Specifically for a 1995 5.0L, we show a "tan wire with a yellow stripe at ignition module" will provide a tach signal. If this is not what you're seeing, give us a call at 815-895-8141 or email us some additional details and our Tech Team should be able to give you more direction: https://www.autometer.com/contacts

Does this work with a wasted spark ignition system? ex: 99 4runner 3.4L V6 with 3 coil packs

Asked by: ngilly
Hi, thank you for the question. Based on the information we have for the 99-00 3.4L, you should not require the 9117 Tach Adapter. On a 1999 3.4L you should have an ignition ignitor on the passenger side of the engine compartment towards the front of the vehicle. Pin # 8 (should be a black wire) of the ignitor should provide a usable tachometer signal for our tachometers and devices that require a tachometer signal.

Hi. I have a Nissan R34 engine which runs individual coils ontop of sparkplugs. I run an aftermarket computer which puts out a RPM signal. I am having trouble getting signal to the tacho. Will this adapter sort out my issue

Asked by: MORK
Hi Mork, thank you for contacting us. This will likely require some additional information and dialogue with our Technical Support Team. It would seem an aftermarket computer that provides a tach signal should trigger our tachometer. If the computer ultimately is not triggering the tachometer, the 9117 may be required. I would recommend reaching out to our Tech Team via the form below and be sure to include as many details as you can, including the tachometer model and year of the Nissan engine. https://www.autometer.com/contacts

Will this work on a motorcycle I have a tachometer with shift lite with 4,6,8 cylinder options that I want to install on my 2017 Harley-Davidson 

Asked by: Street bob
Hi Bob, thank you for contacting us. All the late model Harley Davidson motorcycles are CAN-bus and not compatible with our tachometers and shift lights. We're currently doing some testing now and may have some confirmed options for you in the near future. If you could please send us an email with your application and request, we'll update you when we've completed our testing: https://www.autometer.com/contacts

What voltage will this module output to the tachometer? I'm going to be using this as a 0-12v variable output for a different application. Will this work?

Asked by: Natesace
Thank you so much for contacting us. This device outputs a 12v square wave at a rate corresponding with the firing of the ignition coils. We have only tested this with our gauges, so while it should theoretically work with any device looking for a 12v square wave, we can't guarantee proper function with anything but an AutoMeter product. Hope this helps!

I have a 73 cuda with a gen 3 hemi swap(6.4L) will this work to make the original tach (ralley dash) work?

Asked by: Kyle Deroshia
Hi Kyle, thank you for the question. While technically and "on paper" this should work, unfortunately it's not something we can recommend or offer any support on if it's attempted. The 9117 Tach Adapter will certainly work with an AutoMeter tachometer, as well as most aftermarket tachometers, but we can't make any guarantees on an original OEM tachometer.
