What is a self-fit box and where do I plug it into my car?The ingenie self-fit box is a small cube shaped device which plugs into the OBD port (or the on-board diagnostics port if you like to be fancy) in your car. It’s super simple to plug this in yourself, but if you’re not sure where your OBD port is, just check out our handy box location checker on our help page.
