• Where to Find Cable Connections on Off-Highway Equipment (Part 2)

    Finding where to connect to run diagnostics on construction and farming equipment is frustrating. It can seem like no two machines have the hook up in the same place. So we have broken down some of the most common equipment that we work on with our Diesel Laptops Diagnostic Kits.

    You may have seen our previous blog post, ‘Finding Where to Connect,’ that laid out the connection locations for a Bobcat Skid Steer, Bomag Roller (Deutz Engine), CAT Dozer, CAT Excavator, CAT Grader, CAT Loader, CAT Skid Steer and CAT Backhoe. If you missed it, you can find it here.

    JLG Aerial Lifts with Duetz Engines

    The connection for these machines is found in one of 3 places: behind the panel, next to the ECM or behind the engine.

    Behind the side panel:

    Most commonly it’s on the back of the engine:

    JCB Excavator

    This is another machine where the connection port changes from model to model. Most frequently it will be found under the seat, engine compartment or behind the seat.

    The diagnostic port for this model is under the seat:
