This compact and easy to install module will allow you to easily adapt AutoMeter tachometers and shift lights and many other aftermarket RPM-based devices on your alternator-equipped diesel or non-standard ignition gasoline engine. Equipped with a sensor which is mounted to the alternator casing, a one time setup calibration is accomplished via push button interface on the module to synchronize the alternator signal with engine crank RPM. Perfect for diesel performance applications looking to add a tachometer or upgrade from factory equipment and a great problem solver for engine swap builds in need of working instruments. Pair it with AutoMeter's low-rev tachometer models to complete your diesel-specific gauge installation.

DIESEL TACH ADAPTER is rated out of 5 by 1.Rated 4 out of 5 by George 58 from Sensor works fine, easy to install. Had to use a 1K pull up resistor for the adapter to work with a VDO tachometer gauge. A circuit diagram of the adapter o/p circuitry would have been helpful.Date published: 2018-04-08
Want to add this to an older military truck M35A2, 24v alternator but I do have 12 volt available by tapping into a single 12v battery. Will it work ??Thank you for your question. The 9112 will work with AutoMeter gauges as long as both the module and the gauge are supplied with 12v power. That being the case, this should work for your application, unless it is not being used with an AutoMeter gauge. We can not guarantee the 9112 will work with any other brand of gauges.Date published: 2018-09-11
I have a New Holland 3 cyl diesel tractor. NH says my alternator reads the alternator RPMs, divides by 10, and sends signal to the electronic tach. My tach has quit working. Will this adapter and one of your tachs work on my tractor and alternator?Hi Mike, thank you for the question. As long as you have 12V on the tractor, yes, the 9112 will work and will trigger any of our tachometers. Just in case the tractor is open, most of our tachometers are not water resistant. Only our Marine tachometers are water resistant on the face only.Date published: 2018-09-06
Will this work on a 1984 Volkswagen Pickup (Caddy) with a 1.6L Turbo Diesel (IDI) engine?Hi Kenny, thank you for the question. The 9112 Diesel Tach Adapter requires 12V and an alternator, so it's basically universal. It's then designed to drive any standard ignition AutoMeter tachometer.Date published: 2018-09-04
Does this work on any alternator or it has to be a specific unit? I have a 91 d250 Ram with a 5.9 Cummins and I want to make sure it works. Also. Do any/all of your tachs work on it?Hi Jose, no specific alternator requirements on the 9112 Diesel Tach Adapter. Any AutoMeter standard or electronic ignition tachometer will work with the 9112. We do offer several 6,000 RPM tachometers that are more suited for a diesel compared to most of our 8-10K tachometer. Those 6K models include 2695, 3996, 3997, 4475, 4476, 5875, 5876.Date published: 2018-08-21
Do the tachs come with the pickups of the aultinator and do they work on all aultinators , do you have any with numbers up to 3000 with the big numbers and how much are theyHi Delmer, thank you for the question. We have two tachometers that come with alternator probes and are designed for diesel trucks; models 2888 and 3788. The 9112 Diesel Tach Adapter will allow you to trigger any standard AutoMeter tachometer off you alternator. We have nothing in a 3000 RPM, but do offer several 6000 RPM options in both 3-3/8" and 5".Date published: 2018-07-13
Hi, I have a 87 f250 ( was a 6.9 ) with a 95 PSD in it. The tach signals are not compatible from what i understand, and i cannot use the stock tach in my gauge cluster. if i installed this would it allow me to read the 95 PSD signal on my 87 tach?Thank you so much for contacting us. We engineered this module to drive AutoMeter tachs and it outputs a 12v square wave signal. While this will probably work with a lot of other tachs on the market, we haven't tested it in any applications other than with AutoMeter tachs. As such, I'd be hesitant to recommend it as a solution to drive your OEM tach. It's possible it might work, but we wouldn't be able to guarantee that it would. Sorry for the bad news.Date published: 2018-07-09
Hi i was wondering how this would work without an alternator? I have a diesel pull truck amd i do not run a alternatorHi Der3k, thank you for the question. Our 9112 Diesel Tach Adapter does require an alternator. For a pull truck application without an alternator, you may have to consider something like our model 6806: https://www.autometer.com/5-tach-6-000-rpm-w-mem-4-pulse-diesel.htmlDate published: 2018-07-02
Will this work with a glowshift tachometers?Thank you so much for contacting us. We don't test any other gauges when developing our products and as such, would be unable to provide any assurances as to compatibility with an imported tach like that. Our tach adapter outputs a 12v square wave which in theory should work with any aftermarket tach, we just wouldn't be able to guarantee it. Hope this helps!Date published: 2018-05-22
