I’ve added a couple of posts about the fuel economy guage recently but in those posts I left out the fact that I already had one device on the ODB-II port of my 2008 Chevrolet Impala – a Zubie vehicle monitoring device that is cloud-connected via its own celluar connection (the one at this link is slightly different from the ones that we have; they are both white and were also purchased as a two-pack – I don’t know if there is any technical difference between the models).
In order to solve this issue I decided to purchase a iKKEGOL 30cm/12″ ODB2 ODB II Splitter Extension Y J1962 16 Pin Cable Male to Dual Female Cord Adapter. I’m not sure why the item name is written as ODB2 ODB II as it should instead be OBD2 OBD II but it does work properly. I read several reviews before deciding to purchase this devices as I was uncertain whether or not having two devices connected in this way would cause issues. I decided that it was not very likely to be a problem because the fuel economy guage only reads from the system and the Zubie device probably rarely ever sends data, if at all.
I haven’t had a single problem with either device since I connected them to the splitter.
The white fabric is actually an elastic material helping to ensure that the connection to the OBD-II port doesn’t slip loose. Normally, the cables are tucked away better but I had just shifted them before taking this cable to reposition the fuel economy guage.
Update 04/18/2018: Using the splitter with these devices worked great and didn’t seem to cause any problems with my vehicle.
I used a dashcam, phone charger and bluetooth adapter in the car for a while but I grew tired of having to manually unplug those devices when not in use or when I turned the car off. Unfortunately, in my 2008 Chevrolet Impala the vehicle would continue to provide power to any plugged in accessories even when the engine was off. Most of these devices are low power but even a dashcam, given enough time, could eventually drain the vehicle batter, especially if the car wasn’t being used for several days.
Re-wiring the electrical system and messing with fuses is beyond my experience so I decided to see if I could find an automotive power strip that would have a built-in power switch and sure enough I was able to find the perfect device.
The EUGIZMO Cigarette Lighter Splitter only costs about $16, offers three DC outlets, four USB power ports, a large power switch for the unit and also a very good visual indicator to show whether or not it is on.
I chose to mount this upside-down, just below the vehicle’s built-in DC power ports. This placement moves most of the power adapters and cables out of the way; whenever I turn the car on or off it’s very easy to just reach down and hit the large power button.
At first affixing the unit beneath the dash was a bit of the problem as the first type of velcro that I had used simply wasn’t holding and it would often come loose during the day. Eventually I ended up using some VELCRO Exterme Outdoor Strips and it hasn’t come loose since.
Updated 04/18/2018: The splitter and power button continue to work perfectly. In addition, the VELCRO has held; it hasn’t come loose yet.
