I wanted to put multiple HUDS and OBD-II scanners on my car so I can monitor my cars data. I recently bought a ACECAR M-12 ( https://amzn.to/3dLFRcS ) and ACECAR M-07 ( https://amzn.to/3d6SuQO ) Heads Up Display units for my Honda. I wanted to try to see if I can have multiple OBD-II devices ON a the same time, so I got a OBD-II splitter cable: https://amzn.to/3mPd0Zu

Apparently, the OBD-II splitter cable: https://amzn.to/3mPd0Zu only talks to one OBD-II device at once. So of the two HUD devices only one received data, while the other only received power. This is good to know if you want multple OBD-II devices powered, however bad if you needed the car data.
