The Transmission ELD uses proprietary software paired with hardware from Geotab. You might find it helpful to watch Geotab's installation video and read instructions below, adapted from Geotab's website.
Changing the adapter on your harness
- Unscrew the screw cap behind the 9-pin connector and slide out of the way.
- Gripping the wires behind the cartridge, remove the connector and adapter together.
- Slide the adapter off the connector and replace it with the desired connector, lining up square notches on adapter and connector.
- Screw in and save remaining adapters.
Connecting the ELD to the OBD port
- Locate the OBD (Onboard diagnostic port) in your truck, usually found under the dashboard on the driver's side. Remove the screws from the plate with a screwdriver to expose the diagnostic connector.
- Connect the diagnostic connector to one end of the 9-pin T-harness. Secure the connection with a zip tie.
- Connect the GO device to the 16-pin side of the harness. You should hear the device beep 6 times in succession if this step is completed successfully.
- Turn on the ignition and wait for all 3 LEDs to light up: red indicates detection, green indicates connection, and blue indicates GPS latch.
- Secure the ELD under the dashboard.
- Coil and zip tie the harness under the dashboard to a permanent location. You can ensure quality data by making sure that the device does not move in any way under the dashboard.
- Place the remaining end of the 9-pin harness in the original port location. Screw in place to complete installation.
