Everything we know about putting GPS trackers, dash cameras and telematics into fleet vehicles, written in plain language by the people who do it every day. Whether you're an installer, a fleet manager who wants to understand the work, or a do-it-yourselfer, start here.
These guides cover the electrical basics that every install depends on: finding the right wires, relays, diodes, resistors, the vehicle data bus, fault codes, and the tools in our kit. Twenty years of install experience, cleaned up and put in one place.
Wiring BasicsThe three wires every GPS tracker or dash cam needs, wire gauge, fusing, grounds, splices, and routing. The rules we hold every installer to.
Tips and TricksHow to find a true ignition wire, use a fuse tap, make splices that last, pull wire behind a dash, and avoid the seven things that cause callbacks.
GPS Tracker InstallWhere to mount the device, plug-in OBD-II and hardwired hookups, heavy trucks, hiding the wire, and testing before you close the dash.
Dash Cam InstallRoad-facing, dual-facing and interior cameras: the driver conversation, windshield placement, routing power around the airbag, aiming, and testing.
RelaysWhat relay pins 30, 85, 86, 87 and 87a do, and wiring diagrams for starter interrupts, trigger reversal, latching relays and more.
DiodesWhich way a diode goes, what amp rating to use, and diagrams for isolating door triggers, splitting outputs and protecting device outputs.
ResistorsHow to read resistor color bands, make a value you don't have, and where resistors show up in fleet vehicle installs.
Data BusHow trackers read engine data through OBD-II, J1939 and CAN bus, what the pins do, and the rules for working near a data bus.
Fault CodesHow to read OBD-II and heavy truck SPN/FMI fault codes, and the before-and-after code check we do on every install.
ToolsThe installer tool kit: meter, crimper, driver, trim tools, fish rod, consumables, and a pre-job checklist.
