Yes. All that is required to install it is to connect it to power (12 volt or 24 volt) using the cable supplied with it to either an accessory outlet (often the cigarette lighter outlet) or another power source and mount it using the supplied double sided tape in a suitable position on the vehicle’s dashboard. There are complete installation instructions, with diagrams, supplied with the speedo. An additional cable for permanent power connection is also provided with the speedo. Adhesive velcro to allow the speedo to be temporarily removed from its mounting position is also provided.
