Review: Keeps my dash cam plugged in. - The OBD2 Splitter is a fantastic choice if you need to run multiple devices from your vehicle's OBD2 port without constant swapping. Its ultra-compact design makes it ideal for tight spaces, ensuring it stays out of the way while providing two fully functional ports. I use 1 port for my dash cam while leaving 1 port for diagnostics, so the mechanics don't have to unplug my camera anymore.
Review: Exactly what I needed to keep one OBD facing OE& one for my OBD-powered mirror. - Worked as hoped to create a 180° pass-thru male, plus a splitting-male in the correct 90° orientation under the dash for my Wolfbox 4A OBD car camera harness. It allowed me the OBD plug&play harness option without requiring me to disconnect every time I need the OBD port for a scan tool etc. The two different 90° orientation-options available allowed having the open/unblocked pass-thru facing the same as the original did, while facing the splitter duplicate for the best connection to the accessory harness - concealed under the dash.

### ⭐⭐⭐⭐⭐ Saves Wear and Tear On The OEM OBD2 Port
*by H***O on January 1, 2026*

I have a 2021 Ram 1500 Classic with aftermarket electric running boards. My running boards draw power and signals from the OBD2 port to function correctly. Bought this splitter so I can hook up my running boards and still have the ability to connect my bi-directional scanner to the truck without having to disconnect my running boards and wear out the OEM OBD2 connection over time. Someone else mentioned this and it should be noted more clearly: There are two types of components that you will probably connect to the OBD2. Active or Passive Passive means that it receives power and/or information but does not send anything back. Active means it can communicate with the modules (computers) and manipulate them such as send signals/commands back (think a bi-directional scan tool). You DO NOT want to use this splitter to connect 2 active units at the same time. My running boards (for all intensive purposes) are passive. It does have a module that controls when to extend/retract the running boards but it is external and does not connect to the canbus or truck (other modules). It gets its power and signals (when the doors are open/closed) from the OBD2 port but that is it. When I connect my scanner, I have one passive (running boards )and one active (bi-directional scanner) unit connected to the OBD2 ports at the same time. You can have 2 passives or 1 passive and 1 active but I wouldn't suggest 2 actives. They could have compatibility issues and possibly cause internal damage to modules trying to communicate simultaneously. Imagine having 2 bi-directional scanners hooked up at the same time. One commands the truck to turn the cooling fan on and the other is commanding not to. You're asking for trouble doing things like this. If you need the ability to connect 2 active units at the same time, but don't want to constantly connect/disconnect both from the OBD2 port, I would suggest some type of splitter with a toggle switch that only allows power/communication 1 at a time. Keeps everything protected this way. Overall, very good splitter that doesn't break the bank for my needs.
