Wire colours by harness type

Spectre Basic/Advanced

Cars, utes, vans — and heavier vehicles on the wide-voltage variant

5-pin wiring harness

RedRequired

Power +12/24 V DC (some units support up to 90 V for trucks & machinery)

BlackRequired

Ground (GND)

YellowRequired

Ignition (switched 12 V ACC)

GreyOptional

Analog input (e.g. fuel level)

WhiteOptional

Relay trigger / immobiliser output

Inputs & outputs
  • Ignition — Ignition input — Yellow wire
  • Analog in — Analog input — Grey wire
  • Output — Open-collector output for relay control — White wire
Immobiliser — White wire

White wire drives a relay coil. Wire via a normally-open relay so the circuit is live when the output is low (fail-safe).

Trucks and machinery with CAN bus integration

8-pin wiring harness

RedRequired

Power +12/24 V DC

BlackRequired

Ground (GND)

YellowRequired

Ignition (switched 12 V ACC)

Green/White stripeOptional

Configurable digital or analog input

WhiteOptional

Configurable digital or analog input

OrangeOptional

Relay output / immobiliser

PurpleOptional

Relay output / auxiliary

GreyOptional

Relay output / auxiliary

Inputs & outputs
  • Ignition — Ignition input — Yellow wire
  • Input A — Configurable digital or analog input — Green w/ White stripe
  • Input B — Configurable digital or analog input — White wire
  • Output 1 — Relay output — Orange wire
  • Output 2 — Relay output — Purple wire
  • Output 3 — Relay output — Grey wire
Immobiliser — Output 1, 2 or 3

Three open-collector outputs available. Wire the chosen output via a normally-open relay so the circuit is live when the output is low (fail-safe). Reserve Output 1 for immobiliser by convention so 2/3 are free for aux loads (siren, lock, etc.).

This unit also reads vehicle CAN bus data where supported — no extra wiring needed for that. Leave any unused wires from the harness disconnected.

Plug-and-play (no wiring)

Plugs straight into your vehicle's diagnostic port

OBD-II port (J1962)

Immobiliser not supported

This unit has no digital outputs — choose a harness-based unit if immobiliser functionality is required.

Power, ignition detection, and vehicle data are all delivered through the OBD-II connector — no external wiring required. Takes under a minute to fit.

Not sure which one you have?

RedRequired

Power (typically +12–30 V DC)

BlackRequired

Ground (GND)

White or YellowRequired

Ignition signal

The colours above are the most common convention, but yours may differ. Contact support with a photo of your unit's label and we'll confirm the exact wiring for your device.

Installation diagrams

These cover the general wiring concepts for harness-based units — the circuit shape is the same across both harness types above, only the exact wire colours differ (see the tables above). Plug-and-play units need none of this.

Spectre tracker 3-wire installation diagram: constant power, ignition, and ground
Red — Constant 12/24V (VCC)
Yellow — tracker ignition wire (fixed); vehicle-side colour varies
Black — Ground (GND)
Spectre tracker 2-wire installation diagram: constant power and ground only, engine detection via firmware
Red — Constant 12/24V (VCC, always on)
Black — Ground (GND)
Ignition pin — not connected
Spectre tracker immobiliser circuit diagram using a normally-closed relay
Red — 12/24V Power
White — Output 1 / DOUT (immobiliser trigger). Grey is analog input — do not use; check device label or confirm with support before connecting
Blue — Starter circuit (via relay); actual vehicle wire colour varies
Black — Ground
Spectre tracker general output control circuit diagram using a normally-open relay
Red — 12/24V Power (constant — feeds VCC + relay coil)
White — Output 1 / DOUT (general actuation). Grey is analog input — do not use; check device label or confirm with support before connecting
Green — Load circuit / pump-generator start signal; actual colour varies
Black — Ground

Accessory note — OBD-II Bluetooth dongle

Mount the dongle within about 50cm of the tracker unit. Bluetooth range is short, and anything further can cause dropped connections or unreliable data. If the vehicle's OBD-II port sits far from where the tracker is hidden, run an OBD-II extension cable to bring the dongle closer instead of relying on distance alone.
