Car Electrical Parts & Auto Electrical Parts for Every Vehicle

Everything You Need Across Electrical & Electronics Parts

CBT Auto Parts organises its electrical range into clear categories so you can move from diagnosis to checkout without digging through irrelevant listings. Below is a quick guide to every collection under Electrical & Electronics Parts, grouped the way a mechanic would actually think about them.

Power & Charging Systems

Batteries

A tired car battery is one of the most common reasons vehicles won't start on a cold morning. Our battery range covers 12V options for passenger cars through to heavy vehicle battery voltage requirements for trucks and 4WDs, with sizing and cold cranking amps matched to your vehicle.

Alternators

Once the engine is running, the alternator takes over, recharging the battery and powering everything from headlights to infotainment. We stock alternators for everyday commuters through to performance and commercial applications, at prices that reflect genuine alternator replacement cost rather than inflated dealer markups.

Battery Chargers

For vehicles that sit idle, or fleets that need to stay charged between jobs, our battery charger range includes trickle chargers and jump starters suited to both cars and trucks.

Inverters

Tradies and long-haul drivers rely on a reliable power inverter to run tools, fridges, or laptops from the vehicle battery. Our inverter range spans compact 12V units through to 24V power inverter options built for truck cabins.

Starting & Ignition

Starter Motors

When the key turns and nothing happens, the starter motor is usually the first suspect. We carry starter motor options for petrol, diesel, and heavy engine applications, including specialist fits for older and commercial vehicles.

Distributors

Older and classic vehicles still rely on a functioning distributor to time the spark correctly. This is one of our most searched categories among owners of 4WDs and vintage models, and we stock distributor caps and full assemblies to suit.

Engine & Vehicle Control

Engine Control Units

The ECU is the brain of the modern engine, managing fuel, timing, and emissions in real time. We supply car ECU units, remap ready modules, and replacements for vehicles showing fault codes linked to engine management.

Control Modules

Beyond the engine, most vehicles run on a network of body and transmission modules. Our control module range includes BCM and TCM units that govern lighting, locking, and gear shift behaviour.

ECU Repair Units

Rather than replacing a faulty unit outright, many drivers choose ECU repair as a cheaper alternative. We offer repair and rebuild services alongside reprogramming support for engine control units that are throwing errors.

Immobiliser Modules

A faulty immobiliser module can leave a perfectly healthy engine unable to start. Our immobiliser range includes replacement modules and bypass kits for common makes affected by security system faults.

Sensors That Keep the Engine Running Smoothly

Cam, Crank & Engine Sensors

Crankshaft position sensors and camshaft position sensors tell the ECU exactly where each piston is, and a failing one often means stalling or a no start condition. This collection also covers throttle position sensor stock for drivers troubleshooting hesitation or poor throttle response, alongside crank angle sensor and MAP sensor options for full engine diagnostics.

Wiring & Electrical Connectivity

Wiring Harnesses

A wiring harness bundles the vehicle's electrical circuits into one manageable loom, and damage here can cause faults across multiple systems at once. We stock plug-and-play wiring harness kits as well as custom looms for audio, lighting, and ignition switch applications.

Wiring Connectors

Every wiring harness relies on solid wiring connectors and terminals to stay reliable. Our range includes electrical connectors, wire nuts, wire crimps, and Anderson plug options for towing and accessory wiring.

Relays

A relay switch controls high-current circuits like headlights and fuel pumps using a low-current trigger. We carry automotive relay units for cars, 4WDs, and trucks, including relay and harness kits for HID and LED lighting upgrades.

Fuses

Fuses protect the entire electrical system from overload, and a blown one is often the simplest fix on this whole page. Our car fuse range covers standard blade fuses through to specialist automotive fuse types.

Fuse Boxes

When the fuse itself isn't the problem, a cracked or corroded fuse box usually is. We stock car fuse box replacements and junction boxes suited to a wide range of makes and models.

Switches

From the ignition switch that starts your car to the electric window switch on the door panel, our switch range covers the daily use components drivers replace most often.

Solenoids

A solenoid converts electrical current into mechanical movement, and this collection includes starter solenoid units as well as heavy duty 12V solenoids for commercial and off road applications.

Dash Displays & Driver Information

Dash Panels

The dash panel houses the electronics behind your gauges and warning lights. We stock dash panel units for passenger vehicles and truck instrument panel options built for commercial cabins.

Instrument Clusters

An instrument cluster is the digital or analogue display that reads out your speed, revs, and fuel level. Our range includes digital instrument cluster upgrades and direct replacements for common European and Japanese platforms.

Smart & Connected Vehicle Technology

Telematics

Fleet operators and everyday drivers alike use a GPS tracking device to monitor location, driving behaviour, and vehicle security. Our telematics range covers hardwired and battery-powered automobile GPS tracker units suited to both personal and commercial use.

Cameras

Reversing and dash mounted cameras have become a practical safety upgrade for most vehicles. This collection covers reverse camera and dash cam options, including hardwire kits for permanent installation.

Why Drivers Choose CBT Auto Parts for Electrical Components

Electrical faults are rarely simple, and getting the wrong part usually means a second delivery, a second install, and a second bill. We built our Electrical & Electronics Parts range around fitment accuracy first, listing parts against actual vehicle data rather than generic categories. Every component, whether it's a starter motor or a wiring connector, is sourced to meet OEM specification, so aftermarket options on this page aren't a compromise on quality. Stock is held and dispatched from within Australia, which means most electrical parts move quickly rather than sitting in customs. If you're unsure which sensor, module, or connector matches your VIN, our support team will confirm fitment before you pay for shipping you don't need.

How to Pick the Right Electrical Part

1. Start with the symptom, not the part name. A slow crank points to the battery or starter motor, while a dead crank often points to a relay or fuse.
2. Check whether the fault is intermittent. Wiring and connector faults tend to come and go with vibration or temperature, while sensor faults are usually consistent.
3. Confirm your vehicle's electrical architecture before ordering a control module, ECU, or instrument cluster, since these are rarely interchangeable across trims.
4. Decide between OEM and aftermarket based on how long you're keeping the vehicle, not just the upfront price.
5. When in doubt, send us your rego or VIN before ordering rather than after.
