Tuners, power steps, digital gauges, etc, all require connection to your OBDII port, and obviously your vehicle only came with one of those.
Well now with this splitter you can have multiple aftermarket products running through your OBDII port at the same time, without having to disconnect one of them every time you want to use something else!
