A semi spends its life on the road, so a tracker that drops out or a harness that works loose is a problem hundreds of miles from the yard. We install GPS tracking devices and ELDs on semis and heavy duty trucks across Georgia, South Carolina, North Carolina, Tennessee, Virginia, Alabama, Florida and Mississippi, on the right harness for the truck, secured behind the dash and tested before the truck rolls.
Fleet installs from $65 per vehicle. Testing a few vehicles first? We do pilot installs too.
Semis and heavy duty trucks do not use the OBD2 port found on cars and pickups. They use a round heavy duty diagnostic port under the dash:
The same ports are found on other heavy duty equipment too, from excavators to tractors. Pinouts and port locations are in our Vehicle Wiring Database.
Most semi installs use a Y-split harness on the 9-pin or 6-pin port. The tracking device connects through the Y-split, which keeps the port free for the shop's diagnostic tools, and the device is mounted behind a dash panel and secured, not left hanging where a boot can knock it loose. Where a fleet wants it, the device is hardwired to constant, ignition and ground instead, with every circuit metered and the power fused.
Placement matters more on a semi than anywhere. The device needs a clear view of the sky through the windshield or dash, and a semi's dash has more metal behind it than a pickup's.
Often, yes. Most drivers of semis have to keep electronic logs, and many tracking devices do both jobs: GPS tracking for the office and the ELD for the driver's hours of service, from the same 9-pin connection. That saves a second device and a second harness on the same port. See our ELD installation page for who needs one and how the driver display is mounted.
Where every tractor is and where it has been, idling time, speeding, harsh braking, engine fault codes from the truck's computer, and engine hours and mileage for service. With the ELD on the same device, the office sees drivers' available hours alongside location. Real-time tracking runs over the cellular network, so it carries a monthly plan from the tracking provider. See all the vehicles we track for the rest of the fleet.
We install all of these on semis and heavy duty trucks, on the 9-pin or 6-pin port. Need heavy duty trackers for trucks or heavy equipment? Every brand below makes them, so pick yours and we install it.
Common questions
No. Semis use a round heavy duty port, the 9-pin on most trucks and the 6-pin on older ones. We bring the matching Y-split harness.
Newer trucks often have a green 9-pin and older ones a black 9-pin, and the harness has to match the port. We check your trucks before the job.
Often, yes. Many devices do both from the same 9-pin connection. Ask your provider before adding a second device.
Yes. We come to your yard or terminal and work around dispatch so trucks are back on the road quickly.
