Note
J1708 support on the LytxOne Gateway is non-diagnostic, it provides vehicle connectivity but does not read full diagnostic fault codes the way J1939 or OBD-II connections do.

Connect the Cable

  1. With the engine off, locate the vehicle's J1708 port, typically beneath the dash or near the driver's seat.
  2. Connect the connector to the vehicle's J1708 port. Push firmly until fully seated.
  3. Confirm the cable is clear of the vehicle's pedals, steering linkage, and other moving parts. Physically operate all pedals through their full range of motion to check.
  4. Connect the Molex connector to the PWR/OBD port on the LytxOne Gateway.
  5. Mount the Gateway in a safe, hidden location under the dash, avoiding areas that may heat up or shift while driving.

To finish the installation, continue to Step 3: Mount & Wire to secure the Gateway and mount the Camera, then Step 4: Activate, Verify, Complete to activate and verify the installation.
