Upgrading your vehicle’s data monitoring system with a Motec Obd2 Display Loom can significantly enhance your driving experience and provide critical insights into your car’s performance. This guide provides a detailed, step-by-step approach to installing your MoTeC OBD2 Display Loom, ensuring a seamless integration and optimal functionality. Whether your Display/Logger is pre-configured or requires setup, follow these instructions to get connected.
Installation for Pre-configured Display/Logger
If your MoTeC Display/Logger arrived pre-configured, the installation process is streamlined for your convenience. Follow these steps carefully:
-
Initial Connections: Begin by connecting your Display/Logger, SLM-C (Shift Light Module – Compact, if applicable), button looms, and GPS unit. It’s crucial to NOT connect the OBD-II To Display Loom at this stage.
-
Power Supply Setup: Utilize the provided cigarette lighter power adapter for initial power. Plug it into a spare power supply socket in your vehicle. If a power socket is unavailable, you’ll need to hardwire the power. Cut off the adapter, and connect the red wire to a fused 12V power source and the black wire to a reliable chassis ground.
-
Ignition Activation: Turn your vehicle’s ignition to the “ON” position.
-
Configuration Check: Locate the red button on the button loom and press and hold it for at least 5 seconds. A successful pre-configuration will be indicated by “OBD-II” displaying on your Display/Logger screen. If “OBD-II” does not appear, do not proceed to connect the OBD-II ECU To Display Loom. Instead, refer to the instructions for non-pre-configured devices in the next section.
-
Final Step: If “OBD-II” is displayed, your installation is nearly complete. You can now proceed to physically connect the OBD-II To Display Loom as described later in the guide, after the section for non-pre-configured setups.
Installation for Non-Pre-configured Display/Logger
For Display/Logger units that are not pre-configured, a few additional steps involving software setup are necessary to ensure proper communication with your vehicle’s OBD2 system.
-
Initial Connections (Same as Pre-configured): Connect the Display/Logger, SLM-C (if needed), buttons, and GPS. Do not connect the OBD-II ECU To Display Loom yet.
-
Power Supply Setup (Same as Pre-configured): Power the device using the cigarette lighter adapter or by hardwiring to a fused 12V source and chassis ground, as described in the pre-configured installation steps.
-
Laptop Connection: Establish a connection between your laptop and the Display/Logger using the Ethernet cable provided with your MoTeC system.
-
Launch Dash Manager: Open the MoTeC Dash Manager software on your laptop.
-
Connection Settings: Navigate to “Tools” in the Dash Manager menu, then select “Connection settings,” and click “Add.”
-
Device Search: Click the “Search” button within the Connection settings window.
-
Device Selection: From the list of connected devices, highlight your device and click “Select.”
-
IP Configuration: Click “OK” on the “new IP screen” that appears.
-
Confirm Connection Settings: Click “OK” again on the “Connection settings” screen to finalize the connection setup.
-
Create New Configuration: Go to “File” in the Dash Manager menu and select “New.”
-
Choose OBD-II Configuration: Select the configuration file that corresponds to your specific Display/Logger model and includes “OBD-II” in its name.
-
Send Configuration to Device: Navigate to “Online” in the menu and select “Send Configuration” to upload the newly selected OBD-II configuration to your Display/Logger.
-
Save Configuration File: Save the configuration file with a descriptive name, for example, “my_obd2_config.”
-
Acknowledge Warnings: Confirm “Yes” or “OK” to any warning messages that may appear during the configuration transfer process.
-
Configuration Verification: Press and hold the red button on the button loom for 5 seconds. Verify that “OBD-II” is displayed on the Display/Logger screen. If it’s not displayed, do not proceed with connecting the OBD-II ECU To Display Loom and contact your MoTeC dealer for assistance.
-
Connect OBD-II Loom: Once “OBD-II” is confirmed on the display, connect the 4-pin DTMF connector on the OBD-II ECU To Display Loom to the main loom connector labeled “ECU.”
-
Locate Vehicle OBD-II Connector: Identify the OBD-II connector in your car. The location can vary, but it’s commonly found in the driver’s footwell, beneath the dashboard. It might be directly accessible or hidden behind a removable panel.
-
Connect to Vehicle OBD-II: Plug the mating connector of the MoTeC OBD-II loom into your vehicle’s OBD-II connector.
-
Final Ignition Check: Turn the ignition to the “ON” position. Check if the engine temperature is displayed on your MoTeC Display/Logger. If it’s not displayed and you are using a MoTeC ECU, consult the ECU settings. For other issues, contact your dealer.
-
Installation Complete: With engine temperature (or other relevant OBD-II data) displaying correctly, your MoTeC OBD2 Display Loom installation is now complete.
Finding Your OBD-II Connector Location
The OBD-II (On-Board Diagnostics II) connector is a standardized port in most modern vehicles (typically from 2007 onwards, and some earlier models). While there’s no universally standard location, the driver’s footwell, under the dashboard, is the most frequent spot. You may need to look under the dash, often near the steering column or towards the center console. In some cases, a plastic cover panel might need to be removed to access the OBD-II socket. Consulting your vehicle’s owner’s manual can also provide specific guidance on the exact location of the OBD-II port in your car.
