Universal TFT LCD Display Motorcycle Speedometer Odometer Tachometer Instrument for 2/4 Cylinder

Didnt come with directions, the rpm signal would cause the speedometer reading to max out no matter wich resistors or diodes installed inline. Plus you can find the same one on aliexpress for 40-50$

Received in box with the actual device and speed sensor but no instructions. Have to look up online to find a guide. Will update once installed with pictures.

Had to re wire to fit my bike. The directions were little more then a piece of paper with the pin outs. And I had to find a different place to pull tach signal from and it's not even correct. I'm waiting on a new speedo unit for my bike before I say the speedo doesn't work with factory applications. Overall it's not a bad unit if you can get it cheep enough and not pay the 115$ price tag they want on eBay for the same item.EDIT: Speedo works with stock bike units. Just needs to be adjusted. On subject of adjustment if you change settings it might change other setting. For example I when setting the speedo it would change my tach settings and my units/mileage. So definitely be wary of changing settings.

No wiring digram included with product and I am unable to find one online. Does anybody know where I can find one?
