Can You Get An Obd2 Splitter to connect multiple devices to your car’s diagnostic port? Absolutely! While a true “splitter” isn’t recommended, an OBD2 replicator or “Y-cable” provides a safe and effective solution. This guide outlines the installation process of an OBD2 replicator, allowing you to connect multiple diagnostic tools or accessories without damaging your vehicle’s system.
Parts and Tools You’ll Need:
- OBD2 Replicator with Mounting Bracket: You can often find a combined kit online, ensuring compatibility.
- OBD2 Splitter (Y-Cable): This allows connection of multiple devices to the replicator. Example
- Mounting Bracket: Example
- Phillips Head Screwdriver
- Small Torx Set
- Trim Removal Tool
- Mini Flat Head Screwdriver
Step-by-Step Installation Guide:
-
Remove Hood Release Handle and Screw: Use the Phillips head screwdriver to remove the hood release handle. A second screw will then be visible; remove it using the appropriate Torx bit.
-
Access the OBD2 Port: Carefully pull back the door weather stripping near the dashboard and remove the black plastic door trim. The kick panel surrounding the OBD2 port is secured by two snap clips. Gently pull it towards the transmission tunnel to detach it. Pro Tip: Remove the snap connector closest to the trunk release and place it in the kick panel for easier reinstallation later.
-
Detach Trunk Release Button: Press the trunk release button from behind to disengage it from the kick panel. Rotate the button to expose the wiring harness clip. Use the mini flat head screwdriver to release the harness. Set the button and kick panel aside.
-
Loosen Lower Dash Panel: Using the Torx set, remove the two screws securing the lower dash panel nearest the door. You only need to remove two out of the three screws. This will provide access to the OBD2 port mounting screws.
-
Remove OEM OBD2 Port: Locate the two Phillips head screws attaching the factory OBD2 port to the car and remove them.
-
Connect Replicator to OEM Harness: Plug the OEM harness into the corresponding connector on the OBD2 replicator.
-
Mount the Replicator Bracket: Attach the first connector on the replicator to the aftermarket bracket using the provided hardware.
-
Connect Auxiliary Devices: Plug your diagnostic tools or accessories into the remaining connectors on the replicator. Carefully position the wiring and connectors within the lower dash area before re-securing the panel.
-
Secure the Bracket: Screw the new bracket into place, ensuring it is firmly mounted.
-
Position the Replicator and Harness: Correct placement of the replicator and harness is critical for smooth reassembly of the kick panel. Ensure the trunk release wiring remains accessible. Refer to the image for optimal positioning.
-
Reinstall Kick Panel: Carefully reattach the kick panel, remembering the trick with the snap connector from step 2. Connect the trunk release button wiring.
-
Final Reassembly: Reinstall the door trim, weather stripping, and the OBD2 access cover in reverse order of removal.
By following these steps, you can successfully install an OBD2 replicator and enjoy the convenience of connecting multiple devices to your vehicle’s diagnostic port. Remember to consult your vehicle’s specific repair manual for any unique instructions or precautions. Using a replicator instead of a simple splitter ensures the integrity of your vehicle’s electrical system and provides a reliable connection for all your diagnostic needs.
