14 AWG M22759/32 Tefzel Wire for Motorsport Wiring
14 AWG M22759/32 Tefzel wire is commonly used in motorsport, performance automotive, race car and custom wiring harness builds where higher-current wiring needs to stay compact, lightweight and reliable.
14 AWG is a practical choice for higher-current circuits where 16 AWG may not provide enough current capacity or voltage-drop margin. It is commonly used for fuel pump feeds, fan feeds, higher-current PDM outputs, relay-fed circuits, lighting circuits, power distribution branches and larger wiring harness runs.
12Volt Motorsports stocks 14 AWG Tefzel wire in common colours for professional harness construction. We are based in Altona Meadows, Melbourne and ship Tefzel wire Australia-wide.
What is 14 AWG Tefzel Wire Used For?
14 AWG Tefzel wire is typically used for higher-current automotive and motorsport wiring circuits. It gives more current capacity and voltage-drop margin than 16 AWG while still being smaller and lighter than many standard automotive cable options.
Typical uses include fuel pump feeds, fan feeds, PDM outputs, relay outputs, larger lighting circuits and power distribution branches. It is not suitable for starter motor wiring or main battery cable, which require larger cable selected for the actual load and run length.
Common 14 AWG Tefzel Wire Applications
| Application |
Suitability |
| Fuel pump feeds |
Commonly suitable for many pump circuits when current draw, run length and voltage drop are confirmed |
| Fan feeds |
May be suitable for some fan circuits, but larger thermofans may need larger wire |
| PDM outputs |
Suitable for higher-current outputs when the current limit protects the wire and load |
| Relay-fed circuits |
Suitable where relay, fuse, terminal and connector ratings are matched correctly |
| Lighting circuits |
Suitable for higher-current lighting circuits depending on load and run length |
| Power distribution branches |
Suitable for smaller branch feeds where total current and protection are confirmed |
| Starter motor or main battery cable |
Not suitable. Use proper battery cable sized for the load, cable length and voltage drop |
How Do I Choose the Right Tefzel Wire Size?
Wire size should be selected based on current draw, circuit 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.
14 AWG is useful for higher-current motorsport wiring, but the circuit still needs to be checked properly. Long cable runs, high-current pumps, large fans and tightly bundled wiring may require a larger wire size to reduce voltage drop and heat.

What Should I Use With 14 AWG Tefzel Wire?
14 AWG Tefzel wire is commonly used with Raychem DR25 heatshrink, adhesive-lined heatshrink, Deutsch DT connectors, Deutsch DTP connectors, power terminals, splice sleeves, labels and harness documentation.
Raychem DR25 is used as the outer harness sleeving. Adhesive-lined heatshrink is used for sealing, splice protection and strain relief. Deutsch DT and DTP connectors are commonly used where serviceable, higher-current motorsport wiring branches are required.

Frequently Asked Questions
Where can I buy 14 AWG Tefzel wire in Australia?
12Volt Motorsports stocks 14 AWG M22759/32 Tefzel wire in Australia in common motorsport wiring colours. We are based in Melbourne and ship Australia-wide.
What is 14 AWG Tefzel wire used for?
14 AWG Tefzel wire is commonly used for higher-current motorsport wiring circuits including fuel pump feeds, fan feeds, PDM outputs, relay-fed circuits, lighting circuits and power distribution branches.
Is 14 AWG Tefzel wire suitable for fuel pumps?
14 AWG can be suitable for many fuel pump circuits, but the correct wire size depends on current draw, cable length, voltage drop, connector rating and circuit protection.
Can I use 14 AWG Tefzel wire for thermofans?
14 AWG may be suitable for some fan circuits, but larger thermofans can require larger wire because of steady current draw and inrush current. Size the circuit based on the actual fan load.
Can I use 14 AWG Tefzel wire for main battery feeds?
No. Main battery feeds and starter circuits require proper battery cable sized for current draw, cable length, voltage drop and protection method.
Do you ship 14 AWG Tefzel wire Australia-wide?
Yes. We ship 14 AWG Tefzel wire to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between.
