When we send your plug-in Ticker device, it'll come with instructions to help you get set up.
The small device plugs into a port in your car called the Onboard Diagnostics (OBD) port, which is what a mechanic uses to run diagnostic testing.
You can find where your OBD is in your car's manual, or at ticker.co.uk/check-device. Just enter your car reg to see a guide to plugging in your device.
