OBD2 Splitter, bbfly-B31 Full 16pin OBDII Port 1 Male Splitter to 2 Female Extension Cable 1.6IN/4CM (B31 1PACK)

TESTING ITEM, BUT AS OF NOW, A FEW WEEKS OF USE, THIS HAS HELPED US GET PAST SOME COM ISSUES WITH THE Y-CABLE STYLE. I WOULD GIVE IT A SHOT. WORKS WITH MOST PROPANE BI-FUEL SYSTEMS AND GPS.

We had something already using the port. This worked great to add our ELD as well

Absolutely perfect. Allows me to run my Scan Gauge 2 and not have to mess with it when I need to plug in a computer. If you have a scan gauge you know their connectors are super tough to unplug and reinstall.

Nice and simple. Sleek size and work as intended.

Watch which way your tee points, I had to rotate mine to mount. Allows me to leave my aftermarket Dakota dash working and use scan tool without disconnecting.

i can see where two devices would be incompatible; needs to be available as a switch .. maybe asking too much. for splitting the power to a second passive device this does the trick.

I needed this because I use 2 Bluetooth apps simultaneously on my car (one to change tune maps on the fly; one to operate an exhaust valve) and didn't want to swap out the obd plug every time. This did the trick. It allows me to change maps, monitor values and change my exhaust valve in seconds rather than much longer if I needed to pull one plug out and plug another in every time. Not to mention it is reducing unneeded wear and tear on my obd port. Just make sure you look at your obd port and see which side is facing out. The smaller side or the larger side and get which one fits in your car. If you have the side port on the adapter facing interior plastic it will be useless and may not even fit at all so check before you order.

Working great 😊 for my application!
