Azuga 2-Wire Hardwired GPS Tracker: Power and Ground Only

← All Azuga products Technical information, lights and sounds →

What it is

The Azuga 2-wire hardwired tracker has just two connections: constant power and ground. Azuga's help article is titled "2-Wired OBD-II Installation Guide," and the Azuga Fleet mobile app lists it as "Hardwired GPS Tracker" along with the 3-wire version. It has a built-in GPS antenna, a plastic housing with optional bolt slots, and a 10 digit serial number.

This page is about what is different from the 3-wire unit. If you want the ignition wire version, go to the 3-wire tracker page.

The two wires

Wire	Function	What Azuga says
Red	Constant power	12 or 24 volts, always live
Black	Ground	0 volts, to a good ground

Azuga says the device must not go on a battery source greater than 24 volts DC. Compared with the 3-wire guide, this is the one that states 24 volt operation plainly.

What is missing compared with the 3-wire unit

There is no white ignition wire. Azuga's 2-wire guide does not explain how the tracker knows the vehicle is on, and we have not found another Azuga page that does. That matters for anything built on engine state, such as idle time and engine hours. We are not saying the unit cannot do it. We are saying Azuga has not told us how, so ask.

Mounting and registering

Hidden, away from moving parts, under the steering column or under the passenger side dash.
At least six inches from metal. The antenna is internal.
Label side up, tie-wrapped. Bolting through the slots is rarely needed.
Park outside with a view of the sky. GPS may not lock in a garage but will after driving in the open.
Register by serial number in the Azuga Fleet app or in Admin, Vehicles on the web. Vehicle names must be unique.

Good fit and what to plan for

A good fit

Vehicles where tapping an ignition wire is awkward, and 24 volt systems under the 24 volt DC limit, where the fleet mainly wants location and trip history.

Plan ahead

Fleets that depend on ignition-based reports, until Azuga confirms how the 2-wire unit handles them. Also fleets that want to use harness features, which Azuga ties to the three-wire hardwired design in its blog.

Extension cable

Azuga's shop lists a 2 wire hardwire extension cable, 1000 mm, part C601-0011. The price listed on shop.azuga.com on 2026-10-21 was $9.99. It is covered on the extension cables page.

Before you leave the vehicle

Two habits apply to every hardwired install. Confirm the wiring diagram that came with the unit matches the unit in your hand, and write down the serial number, the wire colors and what the lights did. If a unit does not report, that record lets Azuga support help you quickly.

Does the 2-wire Azuga tracker work on 24 volt vehicles?

Azuga's 2-wire guide says the red wire is 12 or 24 volt constant power, and that the device must not be installed on a battery source above 24 volts DC.

Why would I choose 2-wire over 3-wire?

Two wires are simpler to connect and leave out the ignition tap. What you give up is not fully explained by Azuga, so ask how the unit decides the vehicle is running before you count on engine hours or idle reports.

What does a blinking red light mean on it?

Azuga says a red light blinking every two seconds means the install failed. Repeat the install steps.

Do I need to be an installer to fit it?

Azuga's 2-wire guide says a shop mechanic or installer will know how to do the work. The wiring is two wires, but the checks matter: a meter on the constant, a clean ground and the right mounting spot.
