22 AWG M22759/32 Tefzel Wire for Motorsport Wiring
22 AWG M22759/32 Tefzel wire is the workhorse of every ECU harness. It covers ECU signal wires, sensor inputs, CAN wiring, relay and PDM triggers, switch inputs, dash wiring and data acquisition circuits, anywhere compact size, low weight and heat resistance matter.
12Volt Motorsports stocks 22 AWG Tefzel wire by the metre for professional harness construction. We are based in Altona Meadows, Melbourne and ship Tefzel wire Australia-wide. M22759/32 is the wire known in the trade as Spec 55 (TE Raychem part series 55A0111), same specification, two names.

Common 22 AWG Tefzel Wire Applications
| Application |
Suitability |
| ECU sensor inputs | Commonly suitable for low current signal wiring |
| CAN wiring | Commonly used when built as a twisted pair and terminated correctly |
| Relay and PDM triggers | Suitable for low current trigger and digital input wiring |
| Switch panel and dash wiring | Suitable for low current switch and signal circuits |
| Injectors and smart coil triggers | High impedance injectors and coil trigger circuits are commonly run in 22 AWG. Confirm current, run length and protection for low impedance injectors |
| Fuel pumps or thermofans | Not suitable. Use a larger wire size selected for the actual load |
How Do I Choose the Right Tefzel Wire Size?
Wire size should be selected on current draw, circuit length, voltage drop, ambient temperature, bundling, connector rating, fuse rating and PDM current limit, not current draw alone. If the circuit carries significant current or runs a long distance through the vehicle, voltage drop may require a larger wire. Neighbouring gauges: 20 AWG.

Frequently Asked Questions
Where can I buy 22 AWG Tefzel wire in Australia?
12Volt Motorsports stocks 22 AWG M22759/32 Tefzel wire in Australia in common motorsport wiring colours, sold by the metre. We are based in Melbourne and ship Australia-wide.
What is 22 AWG Tefzel wire used for?
ECU signal wiring, sensor wiring, CAN wiring, relay triggers, PDM triggers, switch inputs, dash wiring and other low current motorsport circuits.
How much current can 22 AWG Tefzel carry?
Around 8 amps for a single conductor in free air with a 30 degrees C rise. Derate for bundled runs, and check voltage drop on long circuits.
Can I use 22 AWG Tefzel wire for CAN wiring?
Yes, when the CAN pair is twisted and the network is terminated correctly. Follow the ECU, dash or device manufacturer's CAN wiring requirements.
Can I use 22 AWG Tefzel wire for injectors or coils?
High impedance injectors and coil trigger circuits commonly run in 22 AWG. Low impedance injectors, long runs and shared feeds often need larger wire. Confirm current draw, run length and protection first.
Is 22 AWG Tefzel wire suitable for fuel pumps or fans?
No. Fuel pumps and thermofans need larger wire selected for the actual current draw, run length, voltage drop and protection method.
Do you ship 22 AWG Tefzel wire Australia-wide?
Yes. We ship to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between.
