I have an 2016 Polaris Slingshot with the GM Ecotec LE9 4 CLY Engine. Will this be the correct part for this and if so how would I wire it?

Asked by: Trikeman
Thank you for reaching out to us. Unfortunately, we do not have specific instructions for the GM 4 cylinder Ecotec, but based on many other late model GMs, the 9117 will most likely be required. It will likely be similar to the LS instructions, but instead of 2 coil power banks, there will be just one on a 4 cylinder.

Hello. will this add on be needed for a 1968 360/390 Ford Fe engine using a D.U.I. ignition system? If not then how do we wire up the new 2891 Tachometer to the D.U.I? Thank you, Rob

Asked by: Robb
Thank you for your inquiry. You will not need the 9117 adapter to connect a 2891 tachometer to your D.U.I. Ignition. Simply connect the green wire from the tachometer to the "Tach" terminal on your distributor.

Hello I have 2 questions 1 my LS3 350Z has a IQ3 dash,it's tach input requires a standard 5–20V, 50% duty cycle square wave signal, will the 9117 work? 2 i have a custom harness, could i use the 12V source off of one bank of injectors ilo of both banks?

Asked by: Bryan_ZDayZ
Hi Bryan, thanks for reaching out to us. Yes, the 9117 does produce a standard tach signal that should trigger your aftermarket dash. The 9117 does have to pick up both banks on an LS application.

I have a 2015 Polaris RZR XP 1000. We got the Cobalt tach to work but it is not reading accurately. Will this help to solve it?

Asked by: fasteddiefrisk
Thank you for your question. None of our gauges are made to be used in applications such as this so it is not uncommon on ATVs/snowmobiles/UTVs to experience issues, however, this does not mean we cannot get our gauges to work for you. We will need to get some more information and go through some further troubleshooting. Please call our tech team at 866.248.6357 and we will be happy to help get your tach working for you.

Will this work on 1997 Dodge Ram 1500 3.9l V6? I wired a ultimate playback in and it’s not getting the signal. Would this be the solution? 

Asked by: Sshirley
Thank you for your question. This should not be necessary for your installation. I recommend calling our tech support team at 866.248.6357 and they would be happy to help get your tach working.

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.
