Certainly as grampa_ss stated will work. But I didn’t want to disconnect the Interceptor gauge every time I wanted to connect the MPVI2 to the OBD port. I use a splitter cable and removed the factory OBD port from under the dash and connected it to the splitter cable and then took one of the two female ports and mounted it in the factory mounting location under the dash, and the other female port on the splitter feeds the AEM gauge with the pass-through and then the Interceptor gauge connected to the pass-through. Everything is tucked up and concealed. So you effectively keep both gauges connected at all times and still have an open port in the factory location available for a scan tool or HPTuners MPVI2.
