16 AWG M22759/32 Tefzel Wire for Motorsport Wiring
16 AWG M22759/32 Tefzel wire is commonly used in motorsport, performance automotive, race car and custom wiring harness builds where durability, heat resistance, chemical resistance and compact harness construction matter.
16 AWG is a practical choice for medium-current circuits where smaller wiring such as 18 AWG or 20 AWG may not provide enough current capacity or voltage-drop margin. It is commonly used for lighting circuits, actuators, small pump wiring, fan control circuits, medium PDM outputs, relay-fed circuits and power feeds within custom wiring harnesses.
12Volt Motorsports stocks 16 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 16 AWG Tefzel Wire Used For?
16 AWG Tefzel wire is typically used for medium-current circuits where the circuit needs more capacity than 18 AWG while still keeping the harness smaller and lighter than standard automotive wiring.
Typical uses include lighting circuits, actuators, solenoids, small pumps, fan control wiring, PDM outputs, relay outputs and short power feeds. Larger fuel pumps, thermofans, main battery feeds and starter circuits usually require larger cable selected for the actual load.
Common 16 AWG Tefzel Wire Applications
| Application |
Suitability |
| Lighting circuits |
Commonly suitable for many medium-current automotive lighting circuits |
| Actuator wiring |
Often suitable depending on actuator current draw and duty cycle |
| Small pump wiring |
May be suitable where current draw, run length and voltage drop are confirmed |
| PDM outputs |
Suitable for medium-current outputs when the current limit protects the wire and load |
| Relay-fed circuits |
Suitable where relay, fuse, terminal and wire ratings are matched correctly |
| Fan control circuits |
May be suitable for control circuits or small fans, but larger thermofans usually need larger wire |
| Starter motor or main battery cable |
Not suitable. Use proper battery cable sized for the load and run length |
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.
16 AWG is useful for medium-current motorsport wiring, but high-current circuits and long cable runs may need a larger wire size. Always check voltage drop and make sure the fuse, relay or PDM output protects the wire and connected device.

What Should I Use With 16 AWG Tefzel Wire?
16 AWG Tefzel wire is commonly used with Raychem DR25 heatshrink, adhesive-lined heatshrink, Deutsch DT connectors, Deutsch DTP connectors, ECU plugs, 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 connectors are commonly used for medium-current circuits, while Deutsch DTP connectors may be used where higher connector current capacity is required.

12Volt Motorsports stocks 16 AWG M22759/32 Tefzel wire in Australia in common motorsport wiring colours. We are based in Melbourne and ship Australia-wide.
What is 16 AWG Tefzel wire used for?
16 AWG Tefzel wire is commonly used for medium-current motorsport wiring circuits including lighting, actuators, small pump wiring, fan control circuits, relay-fed circuits, PDM outputs and power feeds.
Is 16 AWG Tefzel wire suitable for fuel pumps?
16 AWG may be suitable for some smaller pump circuits, but many fuel pumps need larger wire depending on current draw, run length, voltage drop, connector rating and protection method.
Can I use 16 AWG Tefzel wire for thermofans?
16 AWG may be suitable for small fans or fan control wiring, but larger thermofans often require larger wire because of steady current draw and inrush current.
Can I use 16 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.
