Buy Automotive Electrical Connectors in Australia
If you are looking to buy automotive electrical connectors in Australia, 12Volt Motorsports stocks connector kits, ECU plugs, terminals, pins and wiring connectors for motorsport wiring, automotive wiring, ECU installs, custom harnesses, engine bay wiring and performance vehicle electrical systems. We are based in Altona Meadows in Melbourne's western suburbs and ship Australia-wide.
Our connector range includes Deutsch connector kits, Deutsch DTM connectors, Deutsch DT connectors, Deutsch DTP connectors, ECU plugs and pins, OEM-style connectors and connectors by pin count.
What Connectors Should I Use for Automotive Wiring?
The correct connector depends on the circuit, current draw, wire size, number of pins, environment and how the harness needs to be serviced. A sensor connector, fuel pump connector, ECU connector and bulkhead connector all have different requirements.
For motorsport and performance wiring, sealed connectors are usually preferred because they protect the electrical connection from moisture, dirt, vibration and harsh engine bay conditions.

Deutsch Connectors for Motorsport Wiring
Deutsch connectors are one of the most common sealed connector families used in motorsport and performance wiring. They are durable, serviceable and available in multiple sizes to suit low-current, medium-current and higher-current circuits.
Use Deutsch DTM connectors for compact low-current circuits such as sensors, ECU signals and switch inputs. Use Deutsch DT connectors for general-purpose automotive wiring. Use Deutsch DTP connectors for higher-current circuits such as fuel pumps, thermofans and larger power feeds.
ECU Plugs, Pins and Harness Connectors
ECU plugs and pins are used for aftermarket ECU wiring, engine management installs, harness repairs and custom ECU loom builds. Correct terminal selection, crimping and wire sizing are critical for long-term reliability.
12Volt Motorsports supplies connector components used with Haltech ECUs, FuelTech ECUs, Holley Dominator ECUs and other custom wiring projects.
What Should I Use With Automotive Connectors?
Automotive electrical connectors are commonly used with Tefzel M22759/32 wire, Raychem DR25 heatshrink, Sumitomo W5DL adhesive heatshrink, Raychem ATUM adhesive heatshrink, engine sensors and professional crimp tooling when building a reliable wiring harness.
For motorsport wiring, the connector should be selected based on current draw, wire size, environment, pin count and serviceability. The correct crimp tool and terminal type are just as important as the connector housing itself.

Frequently Asked Questions
Where can I buy automotive electrical connectors in Australia?
12Volt Motorsports stocks automotive electrical connectors in Australia including Deutsch DTM, DT, DTP, ECU plugs, pins and OEM-style connectors. We are based in Melbourne and ship Australia-wide.
What connector should I use for motorsport wiring?
For motorsport wiring, Deutsch DTM, DT and DTP connectors are common choices. DTM suits low-current sensor and ECU signal wiring, DT suits general automotive wiring, and DTP suits higher-current circuits.
What is the difference between Deutsch DTM, DT and DTP?
Deutsch DTM connectors are compact and suited to low-current circuits. Deutsch DT connectors are larger and suited to general-purpose automotive wiring. Deutsch DTP connectors are larger again and suited to higher-current circuits such as fuel pumps, fans and power feeds.
Are Deutsch connectors waterproof?
Deutsch DTM, DT and DTP connectors are sealed connectors designed for harsh environments. When assembled correctly with the correct terminals, seals and wedges, they provide strong protection against moisture, dirt and vibration.
What connector should I use for sensor wiring?
Deutsch DTM connectors are commonly used for sensor wiring, ECU signal wiring and compact low-current harness branches. The correct connector depends on the sensor, wire size, pin count and environment.
What connector should I use for fuel pumps or thermofans?
Deutsch DTP connectors are commonly used for higher-current circuits such as fuel pumps, thermofans, water pumps and larger power feeds. Always check current draw, wire size and connector rating before choosing the connector.
Do I need a special crimp tool for automotive connectors?
Yes. Professional automotive connectors should be crimped using the correct tool for the terminal type. Poor crimping can cause voltage drop, heat, intermittent faults and long-term reliability problems.
Do you ship automotive connectors Australia-wide?
Yes. We ship automotive electrical connectors to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between.
