M22759/16-14 Black/Blue Stripe Tefzel Wire – 14 AWG ETFE MIL-SPEC Wire for Switched Output and Control Circuits
The M22759/16-14-06 is a 14 AWG Tefzel ETFE aerospace-specification wire with a black base and blue tracer stripe, supplied pre-spooled for professional motorsport harness construction. Black/blue stripe wire occupies a clear and distinct position in the M22759 colour identification spectrum, providing strong visual contrast in a dense harness bundle and a reliable identifier for specific circuit categories in professionally built race car and performance vehicle wiring systems across Norway, Sweden, and Denmark.
Black/Blue Stripe: Switched Output and Secondary Circuit Identification
In motorsport harness identification practice, blue is frequently assigned to switched output circuits, secondary power feeds, lighting system circuits, and diagnostic communication lines – circuits that need to be clearly distinguishable from primary power (red/orange), earth returns (black/green), and signal wiring (yellow/white). The black base with blue stripe at 14 AWG marks this as a medium-current switched output conductor – a relay output feed, a secondary fan circuit supply, a lighting system main feed, or a similar medium-current switched circuit in the vehicle’s electrical architecture.
Tefzel Insulation at 14 AWG: Weight and Performance Benefits
At 14 AWG, Tefzel ETFE insulation provides a wire that is noticeably lighter and more compact than TXL or GXL automotive wire of the same gauge. In a full race car harness with hundreds of conductors, the cumulative weight saving from using Tefzel throughout the build is substantial – a meaningful performance advantage in weight-sensitive motorsport classes where every kilogram of electrical system weight has a direct effect on lap time.
