M22759/32 Tefzel Wire for Motorsport Wiring
M22759/32 Tefzel wire is commonly used in motorsport, performance automotive, race car and custom wiring harness builds where compact size, low weight, heat resistance, chemical resistance and long-term reliability matter.
12Volt Motorsports stocks M22759/32 Tefzel wire in common motorsport wiring sizes and colours. It is suitable for ECU wiring, sensor wiring, CAN wiring, injector wiring, ignition wiring, PDM wiring, switch inputs, relay triggers, solenoids, pumps, fans and full vehicle harness builds.
We are based in Altona Meadows, Melbourne and ship Tefzel wire Australia-wide.
What is M22759/32 Tefzel Wire?
M22759/32 is a lightweight, high-performance wire commonly used in motorsport and harsh-environment wiring. It uses a thin-wall ETFE insulation, commonly referred to as Tefzel, over tin-plated copper conductors.
Compared with standard automotive wire, M22759/32 Tefzel wire is smaller, lighter and better suited to professional harness construction where heat, vibration, fluids, abrasion and packaging space are important.
Tefzel wire is commonly used with Raychem DR25 heatshrink, adhesive-lined heatshrink, moulded boots, Deutsch connectors, ECU plugs, splices, labels and professional harness documentation.
What Size Tefzel Wire Should I Use?
Wire size depends on current draw, run length, voltage drop, ambient temperature, bundling, connector rating, terminal rating, fuse rating and PDM current limit. Do not choose wire size from current draw alone.

What Should I Use With Tefzel Wire?
Tefzel wire is normally used as part of a complete motorsport wiring system. It is commonly paired with Raychem DR25 heatshrink, Raychem SCL, Raychem ATUM, Sumitomo W5DL adhesive heatshrink, moulded boots, Deutsch connectors, ECU plugs, splices, labels and proper harness documentation.
Raychem DR25 is used as the outer harness sleeving. Adhesive-lined heatshrink is used for sealing, splice protection and strain relief. Deutsch connectors and ECU plugs provide serviceable connection points. Labels and documentation make the finished harness easier to fault-find, service and modify later.

Frequently Asked Questions
Where can I buy M22759/32 Tefzel wire in Australia?
12Volt Motorsports stocks M22759/32 Tefzel wire in Australia in common motorsport wiring sizes and colours. We are based in Melbourne and ship Australia-wide.
What is Tefzel wire used for?
Tefzel wire is used for motorsport wiring, ECU wiring, sensor wiring, CAN wiring, injector wiring, ignition wiring, PDM wiring and custom harness builds where compact size, low weight, heat resistance and reliability matter.
Is M22759/32 Tefzel wire suitable for ECU wiring?
Yes. M22759/32 Tefzel wire is commonly used for aftermarket ECU wiring, sensor wiring, CAN wiring, switch inputs, relay triggers and professional motorsport harness construction.
What size Tefzel wire should I use?
The correct wire size depends on current draw, run length, voltage drop, connector rating, terminal rating, circuit protection, ambient temperature and bundling. Common motorsport wiring sizes include 22 AWG, 20 AWG, 18 AWG, 16 AWG, 14 AWG and 12 AWG.
Is Tefzel wire better than normal automotive wire?
For motorsport and professional harness work, Tefzel wire is often preferred because it is compact, lightweight, heat resistant and chemically resistant compared with standard automotive wire. Standard automotive wire may still be suitable for basic applications, but Tefzel is commonly used where packaging, durability and reliability matter.
Do wire colours have fixed meanings?
No. Tefzel wire colour allocation is up to the installer, workshop standard or harness documentation. Colour should be used consistently and recorded in the wiring documentation, but there is no universal rule that one Tefzel colour must be used for one specific component.
Do you ship Tefzel wire Australia-wide?
Yes. We ship Tefzel wire to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between.
