I think the reason why most of you are having problems is because you followed the instructions. They are wrong. Black wire goes to ground not “positiveâ€. Mine works fine! I noticed that before installing. If you put the black wire to a 12v positive wire you’re definitely going to have problems lol. It’s cheap. Does the job for my 90’s ride. Works just fine

Initially, this product was received as advertised Unit worked well and the installation was fairly easy.That being said, only time will tell it's true quality.

I picked this tach for a short term replacement. It’ll do just that . It’ll lose its memory from time to time . As well as needle shake or spike up for no reason, then settle back down . Never could figure out the color change . I wouldn’t recommend this product to anyone.

I was hesitant on making this purchase as some of the reviews made me nervous. It was a quick 20min install for me and it works great. Very happy with it!

The included wiring harness has very thin wires as well as being very short so is more difficult to connect to thicker wiring harnesses. As someone else pointed out there is no cylinder switch on the back as that is done with the push switch on the front. The same switch also adjusts the brightness of the backlight.You need to wire this carefully as a good solid ground and power source are necessary or it does not work.When you turn on the key, the needle will jump bottom to top and back again, making you think it is going to break. But it seems to be designed that way. Not sure about the accuracy but I will test that someday. Seems acceptable.The shift light is just a triggered switch that turns on the red light when it hits the limit adjusted by a rather flimsy turn control on the front face. I would not race with it but it is good to tell me my old engine is beginning to hit dangerous revs on the highway.The mounting bracket has 3 holes for you to put screws through and ruin your dash. It also has a curved center that makes it easier to place on a steering column. But there is nothing to use as a bracket to hold it to the column. Zip ties I guess is what I am trying.
