Since 1957, AutoMeter has set the standard in performance, accuracy and durability with their legendary Tachometers. The absolute pinnacle of engineering and technology, it’s no wonder AutoMeter can lay claim to more motorsports victories than every other gauge manufacturer combined. The patented air core meter movement, wound in house to exacting standards, can move the needle from 0 - 10,000 rpm in 333 milliseconds. An inaugural inductee to the Hot Rod Speed Parts Hall of Fame, no other tachometer on the market has had anything approaching its impact on professional racing. Built for a lifetime of service under the harshest conditions, this is the no compromise tach for no compromise builds. When you’re ready for the best, there isn’t another choice.

I want all the functions to be on the tach. It does not appear that this is the case. It looks like another place is needed to put the selector. Am I right???

Asked by: Maggie
Thank you for your question. Yes, to keep the gauge water resistant, the switch is on the outside. The setup of the switch as well as dimensions for the gauge can be found in the instructions here: https://www.autometer.com/media/manual/2650-1142.pdf

I think it is but, I'll ask the question. No harm in asking a question. This tach is electronic, NOT mechanical, right? Does it come with its own little wiring harness??? How is the 5" measurement obtained.

Asked by: Maggie
Thank you for your question. This tachometer is electric. We have actually never offered a mechanical tachometer. It does not come with a wiring harness, you would have to supply your own wire, we recommend 16-18 gauge wire. The 5" measurement is the Outside Diameter of the bezel.
